Question

At the county fair, 12% of the

people who attended received
free water bottles. If 1,500 people
received free water bottles, how
many people went to the fair?

Answer 1

12,500 people went to the fair.

Explanation:

Set up an equation:

Variable x = number of people who went to the fair

12/100 = 1500/x

Cross multiply:

12 × x = 100 × 1500

12x = 150000

x = 12500

Check your work:

12500 × 12%

Convert percentage into a decimal:

12500 × 0.12

1500

1500 people received water bottles so this is correct!
