Answer:

They had 4 large popcorn and 10 large fountain drinks

Step-by-step explanation:

The picture of the question in the attached figure

I think the price of the large popcorn is $7.50 and the price of the large fountain drink is $5.50 (The picture is not clear)

Let

x ----> the number large popcorns

y ----> the number of large fountain drinks

we know that

$x+y=14$ ----> equation A

$7.50x+5.25y=85$ ----> equation B

Solve the system by graphing

Remember that the solution of the system of equations is the intersection point both graphs

using a graphing tool

The solution is the point (4,10)

see the attached figure

therefore

They had 4 large popcorn and 10 large fountain drinks
