Question

Twelve percent of yesterday’s customers purchased premium-grade gasoline from GasCo. If 24 customers bought premium-grade gasoline, how many customers were there all together?

Answer 1

There are 20 customers all together.

Explanation:

Let x = the total number of customers.

12% of what number is 24. 12% as a decimal is .12

.12x = 24 Divide both sides by .12

`(.12x)/(.12)` =
`(24)/(.12)`

x = 200
