Question

A city has a population of 390,000 people. Suppose that each year the population grows by 5.5%. What will the population be after 7 years?

Use the calculator provided and round your answer to the nearest whole number.​

Answer 1

Exponential growth formula:

Total = start value x ( 1 + percentage)^ time

Total = 390,000(1+ 0.055)^7

Total = 390,000(1.055)^7

Total =567,324.87

Rounded = 567,325
