This question tests middle school problem-solving skills, specifically identifying relevant information and planning a solution path in word problems. This skill involves discerning necessary details from extraneous data and logically sequencing steps to solve problems, crucial for real-world applications. In this scenario, Jordan buys a notebook ($12) and a hoodie ($20 with 25% off), pays 8% tax on the discounted total, and uses a $5 gift card - the $15 hat is irrelevant since it's not purchased. Choice B is correct because it accurately identifies the steps: ignore the unpurchased hat, discount the hoodie (25% off $20 = $5 off, so $15), add the notebook and discounted hoodie ($12 + $15 = $27), apply 8% tax ($27 × 1.08 = $29.16), then subtract the gift card ($29.16 - $5 = $24.16). Choice A incorrectly suggests discounting the total at the end rather than just the hoodie, while Choice C wrongly applies tax before the discount. To help students: teach them to identify what's actually purchased versus what's just mentioned, practice breaking down multi-step problems systematically, and emphasize reading carefully for specific discount applications.

This question tests middle school problem-solving skills, specifically identifying relevant information and planning a solution path in word problems. This skill involves discerning necessary details from extraneous data and logically sequencing steps to solve problems, crucial for real-world applications. For the bake sale profit calculation, we need revenue (60 × $1.50 = $90) minus costs (ingredients $28 + table $12 + flyers 20 × $0.10 = $2, total $42), giving $48 profit. Choice A is correct because the planned but not held talent show is completely irrelevant to the bake sale calculations - it doesn't affect revenue or costs. Choices B, C, and D all identify information that is actually needed: ingredient and table costs affect expenses, cupcake count and price determine revenue, and flyer costs are part of expenses. To help students: teach them to identify what actually happened versus what was merely planned, practice distinguishing between related and unrelated events, and emphasize focusing on the specific activity being analyzed.

This question tests middle school problem-solving skills, specifically identifying relevant information and planning a solution path in word problems. This skill involves discerning necessary details from extraneous data and logically sequencing steps to solve problems, crucial for real-world applications. The class's total cost requires: kit cost (4 × $18 = $72), apply 15% discount to kits ($72 × 0.85 = $61.20), add shipping ($12), apply 5% tax to discounted kits only ($61.20 × 0.05 = $3.06), for a total of $61.20 + $12 + $3.06 = $76.26. Choice B is correct because it identifies all critical components: kit count and price for the base cost, discount rate for savings, shipping as an additional cost, and the tax rule specifying tax applies only to discounted kits. Choice A incorrectly includes irrelevant information about out-of-stock items and markers, Choice C omits crucial kit information, and Choice D suggests an incorrect calculation sequence. To help students: teach careful reading of tax and discount applications, emphasize identifying what's actually purchased versus mentioned, and practice multi-step problems with conditional rules.

This question tests middle school problem-solving skills, specifically identifying relevant information and planning a solution path in word problems. This skill involves discerning necessary details from extraneous data and logically sequencing steps to solve problems, crucial for real-world applications. Leah's purchase involves pens (3 × $2 = $6), a binder ($8 with 10% off), and 6% tax on the discounted total - the unpurchased notebook is irrelevant. Choice B is correct as the first step because it properly identifies ignoring the unpurchased notebook and focusing on finding the binder's discounted price (10% off $8 = $0.80 off, so $7.20). Choice A incorrectly suggests applying tax before the coupon discount, Choice C wrongly includes the unpurchased notebook, and Choice D suggests unnecessary rounding. To help students: teach them to identify the logical sequence of operations (discounts before tax), emphasize reading for what's actually purchased, and practice breaking complex problems into ordered steps starting with identifying relevant items.

This question tests middle school problem-solving skills, specifically identifying relevant information and planning a solution path in word problems. This skill involves discerning necessary details from extraneous data and logically sequencing steps to solve problems, crucial for real-world applications. The builder's material cost includes only what's actually used: 30 boards at $4 each ($120), 2 nail buckets at $9 each ($18), and the $15 delivery fee - the $6 boards and work time are irrelevant. Choice C is correct because it identifies exactly these three cost components: boards used + nail buckets + delivery fee = $120 + $18 + $15 = $153. Choice A incorrectly suggests including work time in material costs, Choice B focuses on unused expensive boards, and Choice D suggests an inefficient approach of adding then subtracting. To help students: teach them to distinguish between material costs and labor time, emphasize reading for what's actually purchased versus what's merely mentioned, and practice categorizing different types of expenses in construction problems.

This question tests middle school problem-solving skills, specifically identifying relevant information and planning a solution path in word problems. This skill involves discerning necessary details from extraneous data and logically sequencing steps to solve problems, crucial for real-world applications. In this scenario, the problem involves flights, layovers, and unrelated airport activities. Choice A is correct because adding both flight durations and the layover provides the steps to find total trip time. Choice B is incorrect because adding yoga class time confuses activities with travel, a common error in sequencing. To help students: Teach them to focus on transit elements, convert all to minutes for addition, and ignore non-travel events. Watch for: students subtracting instead of adding or mixing costs with times.

This question tests middle school problem-solving skills, specifically identifying relevant information and planning a solution path in word problems. This skill involves discerning necessary details from extraneous data and logically sequencing steps to solve problems, crucial for real-world applications. In this scenario, the problem involves buying items with discounts, taxes, and unrelated details like a magazine and cashier name. Choice A is correct because book price, game price, discount rate, and tax rate are essential for computing the total payment. Choice B is incorrect because magazine price and cashier’s name are irrelevant, a common mistake when including all mentioned elements. To help students: Teach them to identify cost-affecting factors, ignore personal or unrelated facts, and practice subtotal calculations. Watch for: students confusing shelf items with purchases or skipping discount applications.

This question tests middle school problem-solving skills, specifically identifying relevant information and planning a solution path in word problems. This skill involves discerning necessary details from extraneous data and logically sequencing steps to solve problems, crucial for real-world applications. In this scenario, the problem details a bake sale with sales, costs, and an unused service offer. Choice C is correct because the DJ music cost that was not used is irrelevant to calculating profit from actual sales and expenses. Choice D is incorrect because ingredient and table costs are essential, not irrelevant, a common confusion when distinguishing used versus unused elements. To help students: Teach them to separate actual from potential costs, list revenues and expenses clearly, and verify irrelevance by checking impact on the total. Watch for: students mistakenly excluding necessary costs or including unpursued options.

This question tests middle school problem-solving skills, specifically identifying relevant information and planning a solution path in word problems. This skill involves discerning necessary details from extraneous data and logically sequencing steps to solve problems, crucial for real-world applications. In this scenario, the problem details a ticket-selling fundraiser with expenses and a free activity. Choice B is correct because multiplying ticket price by tickets sold, then subtracting expenses, finds profit accurately. Choice C is incorrect because adding the free game's value assumes revenue, a common misinterpretation. To help students: Teach them to calculate revenue from sales, list and sum expenses, then subtract. Watch for: students incorporating free elements as costs or revenues incorrectly.

This question tests middle school problem-solving skills, specifically identifying relevant information and planning a solution path in word problems. This skill involves discerning necessary details from extraneous data and logically sequencing steps to solve problems, crucial for real-world applications. In this scenario, the problem details garden purchases with item-specific discounts, delivery, and unpurchased items. Choice B is correct because it sequences discounting only the bricks, adding soil, and including delivery to find the total cost accurately. Choice D is incorrect because it includes the unpurchased stepping stones, a common error when students add all listed prices without filtering. To help students: Teach them to apply discounts selectively, list steps in order like discount then add fees, and cross out irrelevant items. Watch for: students applying discounts broadly or forgetting additional fees like delivery.
