Question

A cafe sells drink in 3 sizes: small,medium and a large. The small cup cost $0.89 and holds 9 ounces. The medium cost $1.29 and holds 12 ounces. The large cost $1.69 and holds 22 ounces. Which size cup is the best buy?

PLEASE HAVE AN EXPLANATION TOO!

Answer 1

The large cup is best to buy. This is because it costs 11 cents per ounce for the medium cup and 11 cents for the large cup as well. You get almost double the amount for the same price with the large cup.
