Population Growth: City A has 800,000800{,}000 people and grows by 1.5%1.5\% per year. City B has 760,000760{,}000 people and grows by 2%2\% per year. After 1 year, Quantity A is City A's population and Quantity B is City B's population. Determine whether Quantity A is greater, Quantity B is greater, or both are equal.

  1. Quantity A is greater. (correct answer)
  2. Quantity B is greater.
  3. The two quantities are equal.
  4. The relationship cannot be determined from the information given.
  5. Quantity B is greater because its growth rate is higher.

Explanation: This question tests the ability to compare quantities without full computation, using algebraic and quantitative methods. The concept involves understanding relationships between quantities and making logical comparisons. Apply this to the stimulus by considering the differences in growth rates and initial values provided. The correct answer works because it accurately reflects the comparison based on the given data, with City A's population of 812,000 exceeding City B's 775,200. A common distractor fails because it misinterprets units or overlooks key assumptions, like assuming higher rate for B wins. Teaching strategies might include practice with estimation techniques and emphasizing the importance of understanding variable roles. Use decimal multipliers.
