You can put this solution on YOUR website! At the fair, Joey bought 3 burgers and two hot dogs for $19. Manuel bought 5 burgers and 3 hot dogs for $30.50. How much are the burgers and hot dogs each?
----------------------------
Equations:
3b + 2h = 19
5b + 3h = 30.5
--------------------------------
Solve for "b":
9b + 6h = 3*19
10b + 6h = 61
----------
b = $4.00 (price of one burger)
--------
Solve for "h":
3b + 2h = 19
3*4 + 2h = 19
2h = 7
h = $3.50 (price of one hot dog)
