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?

15,267

Step-by-step explanation:

To solve this problem, lets use the exponential growth formula which is:

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% -> -> 0.035

Lets plug in the values:

The population after 7 years will be 15,267.

step-by-step explanation:

the triangles are similar. therefore the corresponding sides are in proportion:

              cross multiply

            divide both sides by 32
