Question

Answer 1

If the city population increases by 25% every year, we can set up this equation:

a(t) = a(1.25)^t

Where a is the initial population and t is the number of years.

Using a = 85000 and t = 5, we get:

a(5) = 85000(1.25)^5

 a(5) = 85000(3.0517578125)

 a(5) = 259,399 rounded to the nearest whole person (answer B)
