A city has a population of 240,000 people. Suppose that each year the population grows by 7.25%. What will the population be after 9 years?

Let's build a population function P(t), where t is the number of years since right now.
P(t) = 240,000(1.0725)^t <-- 7.25% as a decimal is 0.0725

The question asks for P(9)
P(9) = 240,000(1.0725)^9
P(9) = 240,000(1.87748)
P(9) = 450,596
