At Bobs diner, it costs $8.00 to purchase two hamburgers and one order of fries. The "family pack" costs 30.00 and comes with six hamburgers and six orders of fries. If the prices are constant,how much does one hamburger cost? Use system of equations to solve.

2H + 1F = 8 ===> F = 8-2H
6H + 6F = 30 or H+F=5
using substitution:
H + F = 5
H + 8-2H = 5
-H = -3
H = 3
then F = 8-6 = 2
each hamburger costs $3.00 and each fries costs $2.00
6H + 6F = 30 or H+F=5
using substitution:
H + F = 5
H + 8-2H = 5
-H = -3
H = 3
then F = 8-6 = 2
