Question

A town has a population of 50,200 and grows at a rate of 9% every year. Which equation represents the town’s population after 2 years?

Answer 1

P = 50200(1+0.09)²

Explanation:

To find the answer to this question we use the equation new value = original value x
`d^(n)`, where d is the multiplier

We are told that our original value is 50200 and to find the multiplier we have to do 1 + 0.09. This is because the population is increasing by 9% which as a decimal is 0.09!

This means that our equation would be P = 50200(1+0.09)²

Hope this helps, have a lovely day! :)
