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

The population of the town after Seven (7) years is 15267.

Step-by-step explanation:

• Make a plan:

We can use the formula of compound interest to solve this problem.

The formula is:

A = P * ( 1 + r )^t

Where A is the final amount.

P is the initial amount.

r is the annual interest rate

t is the number of years.

• Solve the problem:

• We can get the annual interest rate

r = 0.035

• We can get the number of years:

t = 7

• We can use the formula:

A = P * r ( 1 + r )^t to calculate the final amount.

A = 12000 * ( 1 + 0.035 )^7 = 15267.35

Add Constants:

A = 12000 * 1.035^7

Add Constants:

A = 12000 * 1.035^7

A = 15267.351153199

Population after 7 years is 15267 when rounded to the nearest whole number.

• Round the final amount to the nearest whole number:

We get the population after 7 years is 15267

• Draw the Conclusion:

The population of the town after Seven (7) years is 15267.

Hope this helps!
