let
h = the cost of a hot dog
c = the cost of a potato chips
A customer buys 4 hot dogs and 5 bags of potato chips for $12.00
4h + 5c = 12
Another customer buys 3 hot dogs and 4 bags of potato chips for $9.25
3h + 4c = 9.25
by solving the system of equations
4h + 5c = 12
3h + 4c = 9.25
we find
h = $1.75
c = $1
