Atown has a population of 18000 and grows at 2% every year. what will be the population after 12 years, to the nearest whole number?

18000 is the 100% and we will be adding 2% to the population every 1 year.

100% + 2% = 102%

Convert the percent into a decimal.

102% = 1.02

For 12 years, the population will increase by 2%.

So, 18000 * 1.02 * 1.02 * 1.02 * 1.02 * 1.02 * 1.02 * 1.02 * 1.02 * 1.02 * 1.02 * 1.02 * 1.02 or 18000 * 1.02^12

18000 * 1.02^12
18000 * 1.26
22680

So, it will be around 22680.
