Question

(Please Answer quickly, parent mad at me!)Sophie earns $12.80 per hour babysitting. She has to repay a loan to her parents in the amount of $100. After repaying the loan, she wants to have at least enough money to buy herself a pair of sneakers costing $130.40. Write an inequality modeling the number of hours, x, Sophie needs to work to have enough money to buy the sneakers.
A. X ≤ 10
B. x ≤ 18
C. x ≥ 18
D. x ≥ 10

Answer 1

She would have to work 11 hours to get enough money to buy the sneakers

But if you want the hours included for the time she needs to work to pay off the loan she would have to work 8 hours, so all together 19 hours

Answer 2

Answer:

Step-by-step explanation:

Let the hours be x

so 12.8x >= 100+130.40

so 12.8x >= 230.4

x >= 230.4/12.8

x >= 18
