The population of a school is 800 students and is increasing at a rate of 2% per year. Use an exponential function to find the population of the school after 9 years.

Answer 1

P(t) = 800(1.02)^t

P(t) = 800(1.02)⁹

Can you calculate and answer?

Answer 2

If it increases by 2%, each year is 102% of the last.

After 1 year, the population is 800(1.02). After 2 years, it's 800(1.02)(1.02), etc.

Go.
