answer:

x = hot dog price

y = hamburger price

5x + 4y = 16.50

4x + 5y = 17.25

4(5x + 4y = 16.50)

20x + 16y = 66

5(4x + 5y = 17.25)

20x + 25y = 86.25

now subtract the equations:

20x + 16y = 66

20x + 25y = 86.25

9y = 20.25

y = 2.25

hamburger is $2.25

4x + 5(2.25) = 17.25

4x + 11.25 = 17.25

4x = 6.00

x = 1.50

hamburgers are $2.25

hotdogs are $1.50
