Question

Kareem inserted 2 quarters into a dryer at a laundromat, and the dryer ran for 12 minutes. At this rate, for how long would the dryer have run if Kareem had inserted 8 quarters instead?

Answer 1

the drier would have run for 48 minutes. it's simple, 2 quarters for 12 minutes, divide 12 by 2. you get 6. multiply 6 by 8, and you get 48...

Answer 2

8/2 = x/12
x = 8/2 *12 = 48
