Atheater company charges $6.50 per ticket for people of all age groups. if c represents the total number of children who bought tickets and a represents the total number of adults who bought tickets, which expression best represents the total money earned by the company from the sale of tickets?

First, let us clarify the given.

C = total no. of children 
A = total no. of adults
T = total sales of the company

The best expression that would represent the total money earned by the company from the sale of tickets would be:

T = 6.50C + 6.50A

This is the best expression since the ticket costs the same for all age groups.

The answer would be b ! explanation: the formula for sa *surface area * is 2×l×w+2×l×h+2×w×h so in this case l=4w=12h=8so you use the formula to solve it and it give you the answer of 352^cm^2
