Answer: The total cost for two people to go to the movies three times is 3x2 = 6x dollars.
The cost of a bag of popcorn is $4 and they share one bag of popcorn each time they go to the movie, so the total cost of popcorn is 4*3 = $12 dollars.
So the total cost for two people to go to the movies three times and sharing a bag of popcorn each time is 6x + $12
So an expression to represent the total cost for two people to go to the movies three times and sharing a bag of popcorn each time is 6x + $12.
