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 dr
stiks02 [169]
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

LUCKY_DIMON [66]
9/19 = x / 152....9 oz oil to 19 gallons gas = x oz oil to 152 gallons gas
cross multiply because this is a proportion
(19)(x) = (152)(9)
19x = 1368
x = 1368/19
x = 72 oz of oil <==
