Question

LUNCH ACCOUNT At the beginning of the quarter, Nahla deposited $100 into her lunch account. If Nahla spends an average of $18 per week on lunches, then m = 100 ‒ 18w represents the amount of money Nahla has left in her lunch account m after w weeks of school.

Answer 1

Answer: m=5

Explanation:

I'm not exactly sure your question but I think you are asking how many weeks she can go without going over the $100 balance. If so she can buy her lunch for 5 weeks after that she will have $10 left.
