Virginia · Answer 1

She needs to work 9 more hours she will have a remainder of $6

Bryanna · Answer 2

8.33≈ 9 hours.

Step-by-step explanation:

She has $45 and she earns $9 per hour. So, the equation is y = 45+9x where y is the price of the ipod and x is the number of hours she need. Now,

120 = 45 + 9x

120 - 45 = 9x

75 = 9x

x = 75/9

x = 8.33.

Then, she need to work 8.33≈ 9 hours more to earn the rest of purchase.
