The population of a town decreases by 500 people per year. In 2020, it was 10,000. What is the population in 2025?

A

7,5007,500

B

8,5008,500

C

12,50012,500

D

9,5009,500

Correct Answer: A

Choice A is the correct answer. Linear decay.

  1. Rate: −500-500.
  2. Time: 2025−2020=52025 - 2020 = 5 years.
  3. Calculation: 10,000−500(5)=10,000−2,500=7,50010,000 - 500(5) = 10,000 - 2,500 = 7,500.

💡 Strategic Tip: Decreases mean subtract.

Choice B is incorrect because only 3 years? Choice C is incorrect because added instead of subtracted. Choice D is incorrect because only 1 year.
