Question

A town has a population of 14000 and grows at 2.5% every year. What will be the population after 5 years, to the nearest whole number?

Answer 1

This is exponential growth. Use the formula P = 14000 (1+0.025)^5.

Note that (1+0.025)^5 = 1.025^5 = 1.131. Mult. the given population, 14000, by this factor to find the answer. Then round off your answer to the nearest whole number.

Answer 2

15750

Explanation:

Initial population of the town is 14000.

Percent increase each year = 2.5%

Increment = 2.5% of 14000

Increment = 2.5/100 × 14000

= 2.5×140

= 350

After five years, increment will be 5×350

= 1,750

Population after five years = initial population + increment

Population after 5 years = 14000+1750

= 15750
