Question

The population of a town is 4,000 people. Every year the population increases by 4%. What will the population of this town be after 7 years?

After 7 years the population of this town will be?

Answer 1

p=c(1+r)^t the population in 7 years will be 5263.72711694

Explanation:

p=c(1+r)^t

p=4,000(1+.04)^t

p=4,000(1.04)^t

p=4,000(1.04)^4

p=4679.43424

p= the population you are solving for

c= the initial amount of the population

(1+r)= the rate of change

t= the period of time

Answer 2

The answer is 5,120

Explanation:

How to find 4% of 4000:

4 times 4000=

16000 divided by 100

160

Then you add 160 to 4000 7 times and you get 5,120.
