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
