Question

A town has a population of 14000 and grows at 2.5% every year. What will be the

population after 5 years, to the nearest whole number?
What’s the answer?

Answer 1

y≈15840

Explanation:

Exponential Functions:

a=starting value = 14000

r=rate = 2.5%=0.025

Exponential Growth:

b=1+r=1+0.025=1.025

Write Exponential Function:

put it all together-

y=14000(1.025)^x

Plug in time for x:

y=14000(1.025) ^5

Evaluate-

y=15839.71498

round-

y≈15840

Answer 2
