Question

In May, Jim’s lunch account has a balance of $58.19. If lunch costs $2.74 per day, how many days will Jim be able to buy lunch before his account runs out of money?

Answer 1

21 days.

Explanation:

To solve this, divide the cost of lunch from the initial amount in his account. Therefore:

58.19 = 2.74x ('x' being the number of days)

Divide both sides by 2.74:

`(58.19)/(2.74) = (2.74x)/(2.74)`

x ≈21.24, or 21 days.

***Since you use whole numbers when counting days, round down to determine the amount of days he can buy lunch. Thus, he can buy lunch for 21 days.
