HELP!
Alex and Leandro purchase two matinee movie tickets. A matinee ticket costs $6.50, a drink costs $5.50, and a bag of popcorn costs $6.00. Define each variable and write an algebraic expression to describe how much they spend based on the number of drinks and bags of popcorn they buy.
I put 6.50m+5.50d+6.00p and 6.50m was marked incorrect. Please help!
