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.

The variables are:

Matinee ticket ⇒ We can call this item as 'm'

Drink ⇒ We can call this item as 'd'

A bag of popcorn ⇒ We can call this item as 'p'

One matinee ticket costs 6.50

Two matinee ticket cost 2*6.50

Three matinee ticket cost 3*6.50

'm' matinee ticket cost m * 6.50 = 6.50m

One drink costs 5.50

Two drinks cost 2*5.50

Three drinks cost 3*5.50

'd' drinks cost d*3.50 = 3.50d

One bag of popcorn costs 6

Two bags of popcorn cost 2*6

Three bags of popcorn cost 3*6

'p' bags of popcorn cost p*6 = 6p

The expression for total cost is given by

Total = 6.50m + 3.50d + 6p
