Hi there! :)

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! :)
