Question

a restaurant charged one customer $18 for 4 cheeseburgers and 3 hotdogs and charged another customer $13 for 3 cheeseburgers and 2 hot dogs. set up the system using 2 variables where c is the number of cheeseburgers and h is the number of hotdogs

Answer 1

4 c + 3 h = 18

3 c + 2 h = 13

-2 ( 4 c + 3h = 18)

3 ( 3 c + 2h = 13)

-8c + -6h = -36

9c + 6h = 39

c = 3

4(3) + 3h = 18

12 + 3h = 18

3h = 6

h=2
