you go to the movies with 5 friends. you and one of your friends each buy a bag of popcorn. the rest of your friends buy just on

vfiekz [6]

The x represents the ticket prices and the y represents the popcorn price. If we distribute the expression, we get 4x +2x + 2y. This shows us that all 6 people bought a ticket, and two bought popcorn. Now plug in the given values and solve.

6*7.25 + 2*3.25 = $50
