Question

A town has a population of 12000 and grows at 3.5% every year. What will be the population after 7 years, to the nearest whole number?

Answer 1

Answer:

15,267

Step-by-step explanation:

To solve this problem, lets use the exponential growth formula which is:$A = P(1+r)^t$

A = total amount

P = original amount

r = growth rate (decimal)

t = years

Before we plug in the values, don't forget to change 3.5% to its decimal form.

3.5% -> $\frac{3.5}{100}$ -> 0.035

Lets plug in the values:

$A=12,000(1+0.035)^7$

$A=15,267$

The population after 7 years will be 15,267.
