Answer:
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 = [tex]\frac{112}{9}[/tex]
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!
