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?

Consider, cost of one bag of cotton candy=x

cost of one souvenir cup = y

Now, 4x+2y=36 , 2x+y=18------(I)

7x+3y=59-------(ii)

in (I), y=18-2x, substitute it in (ii),

7x+3(18-2x)=59

7x+54-6x=59

x=5, substitute it in equation (I),

2(5)+y=18

y=8....ANS

IT Is 8 dollars the letter D because I just got it right on my test
