DAY 411

Instead of buying 4 hamburgers and 3 drinks for $14.50, Ralph buys 3 hamburgers and 4 drinks for $13.50. What is the price of each hamburger and each drink?

Answer:

Each hamburger is $2.50 and each drink is $1.50.

7 hamburgers and 7 drinks would cost $28.00.
1 hamburger and 1 drink cost $28.00/7 = $4.00.
