Answer:

Cost of large popcorn = 4

Cost of small drinks = 3

Step-by-step explanation:

Given that :

Let cost of large popcorn = x

Cost of small drinks = y

Cost of 2 large popcorn and 4 small drinks

2x + 4y = 20

2x + 2y = 14

x + 2y = 10 - - - (1)

x + y = 7 - - - (2)

Subtract :

2y - y = 10 - 7

y = 3

Substitute y = 3 into (2)

x + 3 = 7

x = 7 - 3

x = 4

Hence,

Cost of large popcorn = 4

Cost of small drinks = 3
