Suppose the population of a certain city is 5473 thousand. It is expected to decrease to 4732 thousand in 50 years. Find the percent decrease.

Question

Find the percent decrease.

Answer 1

Percent change = (New - Original) / Original * 100

Original = 5473 thousand

New = 4732 thousand

Percent change = (4732 - 5473) / 5473 * 100 = (-741) / 5473 * 100

= -0.13539 * 100 = -13.539% decrease

Answer 2

First, you will need to find the amount that the population has decreased by subtracting 5473-4732=741.

Then, you can solve this by setting it up as a proportion.

741/5473 = x/100 (x represents the percent decrease)

You will cross multiply to get:

74100 = 5473x

Then, divide both sides by 5473 to find x.
