You are in charge of buying T-shirts for your school’s math club. There are 27 club members, who will each receive a shirt. The T-shirts come in boxes. Each box contains 4 T-shirts and costs $23.50. What is the total cost for the T-shirts?

There are 27 club members, and each will receive a T-shirt. Each box contains 4 shirts, so:

7 boxes of T-shirts will be ordered (since a whole number of boxes must be ordered). Each box costs $23.50, so the total cost for all the shirts is:
7×$23.50 = $164.50
