Question

Write an exponential function to model the following situation.

A population of 130,000 grows 4% per year for 15 years.
How much will the popluation be after 15 years?
Write an exponential function in terms of x.
х
y=10

Answer 1

234000

Explanation:

Given data

population =130,000

Rate=4%

Time= 15 years

The expression for the growth is

y=P(1+r)^x

substitute

y=130000(1+0.04)^15

y=130000(1.04)^15

y=130000*1.800

y=234000

Hence the new population figure is 234000
