Question

After a baseball game, both the winning and losing teams went to the same fast food restaurant. The winning team bought 24 hamburgers and 18 orders of french fries for a total cost of $88.50. The losing team bought 28 hamburgers and 9 orders of french fries at the same restaurant for a total cost of $88.25. What is the cost of one hamburger at this restaurant?

Answer 1

24h + 18f = 88.50
28h + 9f = 88.25.....multiply by -2
---------------------
24h + 18f = 88.50
-56h - 18f = - 176.50 (result of multiplying by -2)
--------------------add
-32h = - 88
h = -88/-32
h = 2.75 <===
