Answer:
She has to wash 12 cars to buy the music ticket.
Step-by-step explanation:
The equation you want to use is 8x + 53.95 >= 145.75
Now, using that equation, you want to find x.
8x + 53.95 >= 145.75
- 53.95 - 53.95
8x >= 91.80
--- --------
8 8
x >= 11.475
But she can not just wash part of a car you want to round up. So she would have to wash 12 cars to but the music ticket.
