Answer:

15 hours.

Step-by-step explanation:

Because her parents are contributing $75 she needs to raise $175. We will divide this by 12 to find how many hours she needs to work. The equation is:

175 / 12 = 14.58

We need to round this up because she is paid by the hour, so she will have to work 15 hours.

Hurry! Remember to do your homework next time! Hope this helps friend.

Answer:

I know the amount needed, the amount contributed, the amount earned per hour

I need to know (I already know everything I need)

My work

250 - 75 - (x * 12) = 0

175 - 12x = 0

12x = 175

x = 6.25

My solution 7 hours, round up from 6.25
