A student believes she can earn between $5200 and $6250 from her summer job. She knows that she will have to buy four new tires for her car at $90 each. She estimates her other expenses while she is working at $660. How much can the student save from her summer wages?

4180 to 5230$

Step-by-step explanation:

1. Lets find the expenses she has to make - > 4*90+660=1020$ (4 new tires + other expenses)

2. As her income is not set strictly we can guess the range she can save (More accurate calculations depends on her strict incomes). We have 5200-1020=4180$ (if she gets paid 5200$) and 6250-1020 = 5230$ (if she gets paid 6250$).

3. So the range of savings vary from 4180 to 5230$$.
