Question

As a club fundraiser,

of students washed 40 cars
one weekend. The next
weekend, they washed 70
cars. What was the percent
increase in the number of
cars washed? how do i set up the problem??

Answer 1

`(70 - 40)/(40)*100`

Explanation:

Use the percent increase formula:

The final value is 70, because that's what they end with.

The initial value is 40, because that's what they start with.

Percent Increase =
`(Final Value - Initial Value )/(Initial Value) *100%`
