A theater sells a combo pack of popcorn, a soft drink, and a movie ticket for $12. For groups of five or more, the theater gives a group discount of $3 per person.

What is the total cost for a class of 30 students?

Please write the mathematical expression for the total cost as well.

Asked by Antzeg

Answer (2)

12 X 30 = 360. 3 X 30 = 90. 360 - 90 = 270. The total cost for a class of 30 students is $270.
If C is cost and S is number of students, the mathematical sentence is: C = S X 12 - (S X 3).

The total cost for a class of 30 students at the theater is $270. This includes applying a group discount of $3 per person from the original $12 combo pack price. The mathematical expression for the total cost is C = S × 12 - (S × 3).
