Question

Kelly went to a hockey game with her family. They bought 4 bags of cotton candy and 2 souvenir cups and spent $36. Marissa’s family went to the same game, bought 7 bags of cotton candy and 3 souvenir cups, and spent $59. How much did one souvenir cup cost at the game?

Answer 1

Let x = cost of cotton candy and y = cost of souvenir cups
The total spent equals x times # of cotton candy bought and y times # cups bought. Can you write that equation for Kelly's family?

Answer 2

$7

$8

$6

$5

Answer 3

those are the answer choices

Answer 4

it is 8

Answer 5

@xXDWEAHXx87, we are supposed to help them figure their problems out, not just give them the answer. The idea is to help them learn, not just finish their homework.

Answer 6

o sorry ill explain

Answer 7

set it as a system of equations:
4x+2y=36
7x+3y=59
divide the whole top equation by two to simplify it:
2x+y=18, now multiply that whole equation by negative 3 so when you add the two equations, the y's cancel out:
-6x-3y=-54
now line up the two equations and add:
-6x-3y=-54
7x+3y=59
x+0y=5
x=5
now plug that in into either equation:
4(5)+2y=36
20+2y=36
2y=16
y=8
Hope that helped!
