Advanced MathEasy–MediumFunction for a growing population
Advanced Math practice question
A town's population is 8,000 and grows by 5 percent each year. Which function gives the population P after t years?
- A. P = 8000(1.05)ᵗCorrect
- B. P = 8000(0.05)ᵗ
- C. P = 8000 + 1.05t
- D. P = 8000(1.5)ᵗ
Answer: A. P = 8000(1.05)ᵗ
Growing by 5 percent multiplies by 1.05 each year.
Why the other answers are wrong
- B. P = 8000(0.05)ᵗ
- Multiplying by 0.05 shrinks the population.
- C. P = 8000 + 1.05t
- This adds a constant, not a percentage.
- D. P = 8000(1.5)ᵗ
- 1.5 is a 50 percent increase.
