You can put this solution on YOUR website! The first time they ordered 3 hamburgers, 5 double cheeseburgers, and 6 jumbo jacks and paid $29.75.
The second time they ordered 2 hambugers, 7 double cheeseburgers, and 5 jumbo jacks at the same price and paid $29.25.
The third time they ordered 4 hamburgers, 4 double cheeseburgers, and 7 jumbo jacks at the same price and paid $32.
What was the price of each type of burger?
-------------
3h + 5c + 6j = 29.75
2h + 7c + 5j = 29.25
4h + 4c + 7j = 32.00
------------------------
Use any method you know to solve this system to get:
h = $1.00
c = $1.75
j = $3.00
-------------------------
