99. Joelle makes $9 each hour she babysits. If a new phone
costs $112, how many hours
must she babysit so that she
has enough money to buy the
phone?

13 hours

Step-by-step explanation:

Put this into an equation where h is hour:

112 = 9h

Divide both sides by 9 to isolate h and find the number of hours needed:

112 ÷ 9 = 9h ÷ 9

h =

h = 12.4

Round up so she has more than the price of the phone rather than less.

This means she must babysit for 13 hours to afford the phone.

Hope this helps!
