Answer 1

Hi there! :)

Answer:

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

Step-by-step explanation:

In order for you to answer your question, you'll need to use the cross product method:

$9         → 2 hours

$31.50  → X hours

(2 × 31.50) ÷ 9 = X hours

63 ÷ 9 = X hours

7 = X hours

There you go! I really hope this helped, if there's anything just let me know! :)

Answer 2

Answer:

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.
