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
