Answer:

The expression : 12x + 2.50y

Total cost = $103.5

Step-by-step explanation:

The number of people that went to the movie = x

Number of people that bought drinks = y

Total cost = 12x + 2.50y

Eight people went to a movie and three of them purchased a drink

Total cost = 12 × 8 + 2.50 × 3

Total cost = 96 + 7.5

Total cost = $103.5
