Answer:

A. it depends on the number of friends who will watch the movie

B. If there are 2 friends the cost of each cinema are exactly same

C. Substitution and elimination method

Explanation:

Let y = the total cost of the cinema + 3 tubs of popcorn

let x = the number of friends

Theater A

y = 14.50x + 3(5.75)

y = 14.50x + 17.25 Equation1

Theater B

y = 13x + 3(6.75)

y = 13x + 20.25 Equation2

substitute Equation1 to Equation2

14.50x + 17.25 = 13x + 20.25

14.50x - 13x = 20.25 - 17.25

1.5x = 3

x = 2

it means that the cost of the cinema + 3 tubs of popcorn are the same if there are 2 friends who will watch the movie
