Question

Jim 3 bought 3 hamburgers and 4 orders of french fries for $10.77 before taxes.
Chris went to the same restaurant and bought 4 hamburgers and 2 french fries for
$10.86 before taxes. What is the cost of one hamburger?

Answer 1

Answer:

The cost of one hamburger is $2.19.

Step-by-step explanation:

Let h = cost of a hamburger

f = cost of a french fries

3h + 4f = 10.77-------->3h + 4f = 10.77

4h + 2f = 10.86------->8h + 4f = 21.72

---------------------

5h = 10.95

h = 2.19, f = 1.05
