Gina bought 5 hot dogs and 3 drinks for 11.50. Renaldo bought 4 hot dogs and 2 drinks for 8.50. How much does each hot dog and drink cost

5h + 3d = 11.50 * 2

4h + 2d = 8.50 * 3

10h + 6d = 23

12h + 6d = 25.50

subtract the former equation from the latter:-

2h = 2.50

h = 1.25

so susbstituting in the second equation

4 (1.25) + 2d = 8.50

5 + 2d = 8.50

2d = 3.50

d = 1.75

hot dogs cost $1.25 and drinks cost $1.75
