Question

A vendor sells hot dogs and bags of potato chips. a customer buys 2 hot dogs and 2 bags of potato chips for $6.50. another customer buys 5 hot dogs and 3 bags of potato chips for $14.25. find the cost of each item.

Answer 1

You have to set a system of equations.

2x+2y=6.50     =     6x+6y=19.5
5x+3y=14.25    =    -10x-6y=-28.5
Hotdogs = 2.25
Potato chips = 1
