Question

I start with $100 in my

bank account and
spend $7.50 a day on
lunch. How many
lunches will I be able to
buy before I run out of
money?

Answer 1

13 lunches

Explanation:

100 divided by 7.5 = 13 1/3

since you have to buy whole lunches, and since we're talking about money, we need to round down to get 13.
