Question

The population of the town was 25,000 people.Then 3,200 people moved away.What was the percent of increase?

Answer 1

-12.8%

Explanation:

To calculate the percent decrease, we:

1. Find the difference between the new value and the original
2. Divide the number by the original
3. Multiply by 100 and the % symbol.

The population of the town originally had 25,000. 3,200 people moved away. This means that the new population is 21,800.

1. 21,800-25,000=-3,200
2. -3,200/25,000=-0.128
3. -0.128(100)=-12.8%

The towns population decreased by 12.8%.
