Ok lets say

popcorn = x and

drinks = y

Jacob: 2x + 3y = 18.25

Zachary: 4x + 2y = 27.50

ok now you have to use these 2 equations to get the answer

4x + 2y = 27.50 - - - > 2y = 27.50 - 4x - - - > y = 13.75 - 2x

2x + 3y = 18.25

2x + 3 (13.75-2x) = 18.25

2x + 41.25 - 6x = 18.25

-4x + 41.25 = 18.25

-4x = - 23

x = 5.75 One bag of popcorn is $5.75

4x + 2y = 27.50

4 (5.75) + 2y = 27.50

23 + 2y = 27.50

2y = 4.50

y = 2.25 One drink is $2.25
