Question

On Tuesday Donovan earned $9 for 2 hours of babysitting on Saturday he babysat for the same family and earned 31.50 how may hours did he babysit on Saturday

Answer 1

To know the answer we'll have to divide 9 by 2 to know how much money Donovan would make in one hour.

9 ÷ 2 = 4.5

So that means Donovan makes $4.05 dollars per hour.

Now we'd divide $31.50 by $4.05 or, 31.50 ÷ 4.5 =

7.

Which means that Donovan babysat for 7 hours.

Hope this helps.

Hi there! :)

Answer:

Donovan babysat for 7 hours on Saturday in order to earn $31.50.

63 ÷ 9 = X hours

7 = X hours
