- A small gym earns total revenue of $90,000. Its explicit costs are $65,000 (rent paid, utilities, and part-time staff). The owner could earn $20,000 working elsewhere and uses a building she owns that she could rent out for $10,000 per year. Based on the firm's cost and revenue information, what is the firm's economic profit?
Answer: $-5,000
This question tests the skill of identifying types of profit in AP Microeconomics. Accounting profit is total revenue minus explicit costs, economic profit is total revenue minus both explicit and implicit costs, and normal profit occurs when economic profit is zero. The small gym has total revenue of $90,000, explicit costs of $65,000, and implicit costs of $20,000 in forgone salary and $10,000 in forgone rental income. The economic profit is $90,000−$65,000−$20,000−$10,000=−$5,000, justifying choice D as the correct answer. A common misconception is to ignore implicit costs, leading to calculating only the accounting profit of $25,000. The transferable strategy is to calculate economic profit as total revenue minus explicit costs minus implicit costs. This method allows you to determine if a business is truly profitable after accounting for all opportunity costs. - Based on the firm's cost and revenue information, is the firm earning normal profit? A firm earns total revenue of $1,500 per week. Explicit costs are $900 for wages and $300 for materials. The owner gives up a $200-per-week wage elsewhere and uses $10,000 of personal funds that could earn $100 per week in interest elsewhere.
Answer: Yes, because economic profit is $0 per week.
This question tests your understanding of types of profit, specifically the concept of normal profit. Accounting profit equals total revenue minus explicit costs, economic profit equals total revenue minus both explicit and implicit costs, and normal profit occurs when economic profit equals zero. The firm has total revenue of $1,500, explicit costs of $1,200 ($900 wages + $300 materials), and implicit costs of $300 ($200 forgone wage + $100 forgone interest). Economic profit = $1,500 - $1,200 - $300 = $0, which means the firm is earning exactly normal profit, confirming answer A is correct. A common misconception is thinking normal profit means the business is failing, when it actually means earning enough to cover all opportunity costs. To determine normal profit, calculate economic profit using: economic profit = TR - explicit costs - implicit costs; if zero, the firm earns normal profit.
- Based on the firm's cost and revenue information, what is the firm's economic profit? A tutoring service earns total revenue of $48,000 and has explicit costs of $30,000. The owner forgoes $12,000 in wages from the next-best job and uses a spare room that could be rented out for $3,000 per year.
Answer: $3,000 per year
This problem requires calculating economic profit for a tutoring service, demonstrating the three types of profit in action. Accounting profit includes only explicit costs, economic profit subtracts both explicit and implicit costs, and normal profit exists when economic profit equals zero. The tutoring service has total revenue of $48,000, explicit costs of $30,000, and implicit costs of $15,000 ($12,000 forgone wages + $3,000 forgone rent). Economic profit = $48,000 - $30,000 - $15,000 = $3,000, confirming answer B is correct. Many students mistakenly calculate only accounting profit ($18,000) by ignoring the opportunity costs of the owner's time and space. The reliable formula for economic profit = total revenue - explicit costs - implicit costs ensures you capture the true profitability above alternative uses. This calculation reveals whether the business generates value beyond what the resources could earn elsewhere.
- Based on the firm's cost and revenue information, is the firm earning normal profit? A tutoring service has total revenue of $60,000. Its explicit costs are $20,000 for rented office space and $10,000 for advertising and supplies. The owner could earn $25,000 working for another tutoring company, and the owner uses $50,000 of personal funds that could earn 10 percent annually in an index fund.
Answer: Yes; economic profit is $0.
This question tests whether you can identify when a firm earns normal profit, one of the three types of profit economists analyze. Accounting profit equals revenue minus explicit costs, economic profit equals revenue minus all costs (explicit plus implicit), and normal profit occurs when economic profit equals exactly zero. The tutoring service has revenue of $60,000, explicit costs of $30,000 ($20,000 rent + $10,000 advertising/supplies), and implicit costs of $30,000 ($25,000 forgone salary + $5,000 forgone interest on $50,000 at 10%). Since economic profit = $60,000 - $30,000 - $30,000 = $0, the firm is earning normal profit. Many students mistakenly think normal profit means the firm earns nothing, but it actually means the firm covers all costs including opportunity costs. The strategy for identifying normal profit is straightforward: calculate economic profit, and if it equals zero, the firm earns normal profit.
- Based on the firm's cost and revenue information, is the firm earning normal profit? A food truck earns total revenue of $55,000 and has explicit costs of $44,000. The owner gave up a $8,000 part-time job and uses $30,000 of personal savings that could have earned $3,000 in interest elsewhere.
Answer: Yes; economic profit is $0, so the firm earns normal profit.
This question asks whether a food truck is earning normal profit, requiring understanding of all three types of profit. Accounting profit considers explicit costs only, economic profit includes all costs (explicit and implicit), and normal profit specifically occurs when economic profit equals zero. The food truck has total revenue of $55,000, explicit costs of $44,000, and implicit costs of $11,000 ($8,000 forgone wages + $3,000 forgone interest). Economic profit = $55,000 - $44,000 - $11,000 = $0, which means the firm is earning exactly normal profit, making answer B correct. A common misconception is thinking zero economic profit means the business is unprofitable—actually, it means the owner is doing exactly as well as they would in their next-best alternative. The transferable strategy: when economic profit = TR - explicit costs - implicit costs = 0, the firm earns normal profit. This indicates the resources are earning their opportunity cost, no more and no less.
- Based on the firm's cost and revenue information, which statement correctly compares accounting and economic profit? Total revenue is $250,000 and explicit costs are $180,000. The owner's implicit costs are $40,000 (forgone wages) and $20,000 (foregone rent on an owner-owned warehouse).
Answer: Accounting profit is $70,000 and economic profit is $10,000.
This question tests your ability to distinguish between types of profit. Accounting profit considers only explicit costs, economic profit includes both explicit and implicit costs, and normal profit occurs when economic profit equals zero. The firm has total revenue of $250,000, explicit costs of $180,000, and implicit costs of $60,000 ($40,000 forgone wages plus $20,000 forgone rent). Accounting profit = $250,000 - $180,000 = $70,000, and economic profit = $250,000 - $180,000 - $60,000 = $10,000, making choice A correct. Students often reverse the profit calculations or forget to include all implicit costs. The systematic approach is: first calculate accounting profit (TR - explicit costs), then calculate economic profit (TR - explicit costs - implicit costs). Economic profit is always less than or equal to accounting profit.
- Based on the firm's cost and revenue information, is the firm earning normal profit? A firm earns total revenue of $1,000 per week. Explicit costs are $500 for wages and $200 for materials. The owner gives up a $250-per-week wage elsewhere and uses a workspace that could be rented out for $50 per week.
Answer: Yes, because economic profit is $0 per week.
This question tests your understanding of types of profit, specifically the concept of normal profit. Accounting profit equals total revenue minus explicit costs, economic profit equals total revenue minus both explicit and implicit costs, and normal profit occurs when economic profit equals zero. The firm has total revenue of $1,000, explicit costs of $700 ($500 wages + $200 materials), and implicit costs of $300 ($250 forgone wage + $50 forgone workspace rental). Economic profit = $1,000 - $700 - $300 = $0, which means the firm is earning exactly normal profit, confirming answer A is correct. A common misconception is confusing normal profit with zero accounting profit, when normal profit actually means positive accounting profit that exactly covers opportunity costs. To identify normal profit, calculate economic profit as TR - explicit costs - implicit costs; a result of zero indicates normal profit.
- Based on the firm's cost and revenue information, what is the firm's economic profit? A small gym earns total revenue of $300,000. Its explicit costs are $180,000 for wages and utilities and $40,000 for lease payments on equipment, for total explicit costs of $220,000. The owner gives up a $60,000 job offer and uses $50,000 of personal funds that could earn $5,000 in interest annually (implicit costs total $65,000).
Answer: $15,000
This question tests your understanding of types of profit in microeconomics. Accounting profit is total revenue minus explicit costs, economic profit is total revenue minus both explicit and implicit costs, and normal profit occurs when economic profit is zero. In this scenario, the gym has total revenue of $300,000, explicit costs of $220,000, and implicit costs of $65,000. Therefore, economic profit is $ 300{,}000 - 220{,}000 - 65{,}000 = 15{,}000 $, which matches choice A. A common misconception is ignoring implicit costs, which would lead to calculating only accounting profit of $80,000 instead of economic profit. To solve similar problems, remember that economic profit equals total revenue minus explicit costs minus implicit costs. This formula helps determine if a firm is earning above, at, or below normal profit.
- Based on the firm's cost and revenue information, which statement correctly compares accounting and economic profit? A car-wash earns total revenue of $110,000 and has explicit costs of $85,000. The owner gives up a $20,000 salary elsewhere and uses land he owns that could be leased for $8,000 per year.
Answer: Accounting profit is $25,000 and economic profit is $-3,000.
This question tests your ability to calculate and compare types of profit for a car-wash business. Accounting profit equals revenue minus explicit costs alone, economic profit equals revenue minus all costs (explicit and implicit), and normal profit occurs when economic profit is zero. The car-wash has total revenue of $110,000, explicit costs of $85,000, and implicit costs of $28,000 ($20,000 forgone salary + $8,000 forgone land lease). Accounting profit = $110,000 - $85,000 = $25,000, and economic profit = $110,000 - $85,000 - $28,000 = -$3,000, confirming answer A is correct. Students often misunderstand that negative economic profit doesn't mean bankruptcy—it means the owner would earn more using their resources differently. The systematic approach: calculate accounting profit first (TR - explicit costs), then economic profit (TR - explicit costs - implicit costs). This method clearly shows how opportunity costs can turn an accounting profit into an economic loss.
- Based on the firm's cost and revenue information, which statement correctly compares accounting and economic profit? A food truck earns total revenue of $150,000. Its explicit costs are $90,000 for food, permits, and labor and $20,000 for truck maintenance and insurance, for total explicit costs of $110,000. The owner gives up $25,000 in wages from an alternative job and uses a parking spot that could be rented out for $5,000 per year (implicit costs total $30,000).
Answer: Accounting profit is $40,000, and economic profit is $10,000.
This question tests your understanding of types of profit in microeconomics. Accounting profit is total revenue−explicit costs, economic profit is total revenue−explicit costs−implicit costs, and normal profit occurs when economic profit is zero. In this scenario, the food truck has total revenue of $150,000, explicit costs of $110,000, and implicit costs of $30,000. Therefore, accounting profit is $40,000 and economic profit is $10,000, which matches the statement in choice C. A common misconception is ignoring implicit costs, which would lead to calculating only accounting profit of $40,000 instead of economic profit. To solve similar problems, remember that economic profit equals total revenue−explicit costs−implicit costs. This formula helps determine if a firm is earning above, at, or below normal profit. - A landscaping firm has annual total revenue of $120,000. Its explicit costs are $70,000 for wages, fuel, and equipment maintenance. The owner works full time without taking a salary but could earn $40,000 working for another company. The owner also uses a truck she owns; she could rent it out to another firm for $6,000 per year. Based on the firm's cost and revenue information, which statement correctly compares accounting and economic profit?
Answer: Accounting profit is $46,000 higher than economic profit.
This question tests the skill of identifying types of profit in AP Microeconomics. Accounting profit is total revenue minus explicit costs, economic profit is total revenue minus both explicit and implicit costs, and normal profit occurs when economic profit is zero. The landscaping firm has total revenue of $120,000, explicit costs of $70,000, and implicit costs of $40,000 in forgone salary and $6,000 in forgone rental income. Accounting profit is $50,000 and economic profit is $4,000, so accounting profit is $46,000 higher than economic profit, justifying choice C as the correct answer. A common misconception is to ignore implicit costs, leading to the belief that accounting and economic profits are equal. The transferable strategy is to calculate economic profit as total revenue minus explicit costs minus implicit costs. This approach helps in comparing the two types of profit accurately.
- Based on the firm's cost and revenue information, is the firm earning normal profit? A photographer earns total revenue of $70,000 and has explicit costs of $52,000. The photographer gave up a $12,000 job and uses $60,000 of personal funds that could have earned $6,000 in interest elsewhere.
Answer: Yes; economic profit is $0, so the firm earns normal profit.
This question asks whether a photographer is earning normal profit, testing understanding of the three types of profit. Accounting profit considers only explicit costs, economic profit includes both explicit and implicit costs, and normal profit specifically occurs when economic profit equals zero. The photographer has total revenue of $70,000, explicit costs of $52,000, and implicit costs of $18,000 ($12,000 forgone job + $6,000 forgone interest). Economic profit = $70,000 - $52,000 - $18,000 = $0, which means the firm is earning exactly normal profit, making answer B correct. A common error is thinking normal profit means the business isn't successful—in fact, it means the photographer is doing exactly as well as their next-best alternative. The key insight: when economic profit = TR - explicit costs - implicit costs = 0, the firm earns normal profit. This indicates efficient resource allocation where the business matches but doesn't exceed opportunity costs.
- Based on the firm's cost and revenue information, which statement correctly compares accounting and economic profit? A landscaping firm has total revenue of $120,000. Its explicit costs are $70,000 (wages, fuel, and supplies) and $10,000 (rent), for total explicit costs of $80,000. The owner forgoes a $25,000 salary at another job and uses a truck that could be leased out for $5,000 per year (implicit costs total $30,000).
Answer: Accounting profit is $40,000, and economic profit is $10,000.
This question tests your understanding of types of profit in microeconomics. Accounting profit is total revenue minus explicit costs, economic profit is total revenue minus both explicit and implicit costs, and normal profit occurs when economic profit is zero. In this scenario, the landscaping firm has total revenue of $120,000, explicit costs of $80,000, and implicit costs of $30,000. Therefore, accounting profit is $40,000 and economic profit is $10,000, which matches the statement in choice B. A common misconception is ignoring implicit costs, which would lead to calculating only accounting profit of $40,000 instead of economic profit. To solve similar problems, remember that economic profit equals total revenue minus explicit costs minus implicit costs. This formula helps determine if a firm is earning above, at, or below normal profit.
- Based on the firm's cost and revenue information, which statement correctly compares accounting and economic profit? A photography business earns total revenue of $60,000. Its explicit costs are $20,000 for travel and editing software and $10,000 for studio rent, for total explicit costs of $30,000. The owner gives up $25,000 in wages at another job and uses a camera that could be rented out for $5,000 per year (implicit costs total $30,000).
Answer: Accounting profit is $30,000, and economic profit is $0.
This question tests your understanding of types of profit in microeconomics. Accounting profit is total revenue minus explicit costs, economic profit is total revenue minus both explicit and implicit costs, and normal profit occurs when economic profit is zero. In this scenario, the photography business has total revenue of $60,000, explicit costs of $30,000, and implicit costs of $30,000. Therefore, accounting profit is $30,000 and economic profit is $0, which matches the statement in choice A. A common misconception is ignoring implicit costs, which would lead to calculating only accounting profit of $30,000 instead of economic profit. To solve similar problems, remember that economic profit equals total revenue minus explicit costs minus implicit costs.

- Based on the firm's cost and revenue information, which statement correctly compares accounting and economic profit? A small gym has total revenue of $160,000 and explicit costs of $120,000. The owner also gives up a $25,000 salary elsewhere and uses a storefront he owns that could earn $10,000 per year in rent.
Answer: Accounting profit is $40,000 and economic profit is $5,000.
This question tests your ability to calculate and distinguish between types of profit for a small gym. Accounting profit equals revenue minus explicit costs only, economic profit equals revenue minus all costs (explicit plus implicit), and normal profit occurs when economic profit is zero. The gym has total revenue of $160,000, explicit costs of $120,000, and implicit costs of $35,000 ($25,000 forgone salary + $10,000 forgone rent). Accounting profit = $160,000 - $120,000 = $40,000, and economic profit = $160,000 - $120,000 - $35,000 = $5,000, confirming answer A is correct. Students often mistakenly ignore implicit costs, thinking the $40,000 accounting profit represents true profitability. The key strategy for comparing profits: first calculate accounting profit (TR - explicit costs), then economic profit (TR - explicit costs - implicit costs). This two-step approach clearly shows how opportunity costs reduce the firm's true economic gain.
- Based on the firm's cost and revenue information, what is the firm's economic profit? A firm earns total revenue of $800 per week. Explicit costs are $300 for supplies and $250 for hired labor. The owner works in the business and gives up a $150-per-week wage elsewhere, and the owner's $2,000 of equipment could be rented out for $40 per week.
Answer: $60 per week
This question tests your understanding of types of profit, specifically calculating economic profit. Accounting profit equals total revenue minus explicit costs, economic profit equals total revenue minus both explicit and implicit costs, and normal profit occurs when economic profit equals zero. The firm has total revenue of $800, explicit costs of $550 ($300 supplies + $250 labor), and implicit costs of $190 ($150 forgone wage + $40 forgone equipment rental). Economic profit = $800 - $550 - $190 = $60, confirming answer C is correct. A common misconception is forgetting to include the opportunity cost of capital equipment that could generate rental income. To solve economic profit problems systematically, use the formula: economic profit = TR - explicit costs - implicit costs, ensuring you account for all resources the owner contributes.
- Based on the firm's cost and revenue information, which statement correctly compares accounting profit and economic profit? A small gym has total revenue of $150,000. Its explicit costs are $70,000 for wages, $30,000 for rent, and $10,000 for equipment maintenance. The owner could earn $25,000 managing another gym, and the owner invested $200,000 that could earn 5 percent annually in a certificate of deposit.
Answer: Accounting profit is $40,000, and economic profit is $5,000.
This question tests your ability to distinguish between types of profit by calculating both accounting and economic profit. Accounting profit equals revenue minus explicit costs only, economic profit equals revenue minus all costs (explicit and implicit), and normal profit exists when economic profit is zero. The gym has revenue of $150,000, explicit costs of $110,000 ($70,000 + $30,000 + $10,000), and implicit costs of $35,000 ($25,000 forgone salary + $10,000 forgone interest on $200,000 at 5%). Therefore, accounting profit = $150,000 - $110,000 = $40,000, and economic profit = $150,000 - $110,000 - $35,000 = $5,000. A common misconception is thinking that positive accounting profit guarantees positive economic profit—this ignores opportunity costs. The key strategy is to calculate accounting profit first (revenue minus explicit costs), then subtract implicit costs to find economic profit. - Based on the firm's cost and revenue information, what is the firm's economic profit? Total revenue is $60,000. Explicit costs are $45,000. The owner forgoes $12,000 in wages from a different job and uses a storefront the owner owns that could be rented to another firm for $6,000 per year.
Answer: $-3,000
This question requires calculating economic profit by considering all types of profit. Accounting profit subtracts explicit costs from revenue, economic profit subtracts all costs (explicit and implicit), and normal profit exists when economic profit is zero. The firm has total revenue of $60,000, explicit costs of $45,000, and implicit costs of $18,000 ($12,000 forgone wages plus $6,000 forgone rent). Economic profit=$60,000−$45,000−$18,000=−$3,000 making choice C correct. A common misconception is calculating only accounting profit ($15,000) by ignoring implicit costs. To find economic profit accurately, use the formula: economic profit=total revenue−explicit costs−implicit costs. Negative economic profit indicates the owner would earn more in their next best alternative. - Based on the firm's cost and revenue information, is the firm earning normal profit? A sole proprietor has total revenue of $900 per month. Explicit costs are $400 for materials and $200 for utilities and other bills. The owner gives up a $250-per-month job to run the business and uses $5,000 of personal funds that could earn $50 per month elsewhere.
Answer: Yes, because economic profit is $0 per month.
This question tests your understanding of types of profit, specifically the concept of normal profit. Accounting profit equals total revenue minus explicit costs, economic profit equals total revenue minus both explicit and implicit costs, and normal profit occurs when economic profit equals zero. The firm has total revenue of $900, explicit costs of $600 ($400 materials + $200 utilities), and implicit costs of $300 ($250 forgone wage + $50 forgone interest). Economic profit = $900 - $600 - $300 = $0, which means the firm is earning exactly normal profit, confirming answer A is correct. A common misconception is thinking normal profit means the firm earns no money, when it actually means covering all costs including opportunity costs. To determine if a firm earns normal profit, calculate economic profit using the formula: economic profit = TR - explicit costs - implicit costs; if the result is zero, the firm earns normal profit.
- Based on the firm's cost and revenue information, which statement correctly compares accounting and economic profit? A firm has total revenue of $10,000 per year. Explicit costs are $6,000 for wages and $2,000 for rent. The owner gives up a $1,200-per-year job to run the firm and uses $5,000 of personal funds that could earn $300 per year elsewhere.
Answer: Accounting profit is $2,000 per year, and economic profit is $500 per year.
This question tests your understanding of types of profit by comparing accounting and economic profit calculations. Accounting profit equals total revenue minus explicit costs, economic profit equals total revenue minus both explicit and implicit costs, and normal profit occurs when economic profit equals zero. The firm has total revenue of $10,000, explicit costs of $8,000 ($6,000 wages + $2,000 rent), and implicit costs of $1,500 ($1,200 forgone wage + $300 forgone interest). Accounting profit = $10,000 - $8,000 = $2,000, and economic profit = $10,000 - $8,000 - $1,500 = $500, confirming answer A is correct. A common misconception is thinking implicit costs don't matter for real business decisions, when they represent genuine opportunity costs. To compare profits systematically, always calculate accounting profit first (TR - explicit costs), then subtract implicit costs for economic profit.
