Question

ou and a friend are heading to the movies. You each buy a ticket and you also want to buy some refreshments. The total cost of admission per person, a, is $7.50 and you spent $15.50 on refreshments. Write an expression to represent the total cost of the trip. Then, find the total cost.

Answer 1

Answer:

Expression: $7.50x + 15.50 = y          Total Cost: $30.50

Step-by-step explanation:

x goes next to 7.50 because it is 7.50 per person, which makes it a variable that varies and can change.

since the expression is $7.50x + 15.50 = y, we just plug x in for 2 because he and his friend are going which is 2 people.

7.50(2) + 15.50 = 30.50
