    The population of a town is currently 22,000. This represents an increase of 40% from the population 5 years ago. Find the population of the town 5 years ago. Round to the nearest whole number if necessary.

    To get the population 5 years ago, we'd discount the current population of 22,000 by 40%. We can write a 40% discount as 1.4.

    Population 5 years ago = 22,000/1.4
    Population 5 years ago = 15,714.29

    Rounding to the nearest whole number, we get 15,714
