A youth group takes a bus to the movie theater. The cost of a drink is $2.25, the cost of popcorn is $3.45, and the cost of a ticket is $7.00. Each student gets a ticket, a drink, and popcorn.

Answer:

12

Step-by-step explanation:

We need to assume that every kid got one order of drink and popcorn to make this answer a lot easier.

Considering we already know that the rental costs, all we need to do is find the number of kids that were there, multiplying every ticket, popcorn, and drink bought per child.

A. 8

100 + (7.00 * 8) + (2.25 * 8) + (3.45 * 8) = 201.6

This is not the final cost of $252.40, therefore it is incorrect.

B. 12

100 + (7.00 * 12) + (2.25 * 12) + (3.45 * 8) = 252.41 or 252.4

This equates to the final cost, therefore making it correct.

If 12 is the answer, then any number higher will be incorrect, cross out C. and D.
