Question

A theater company charges $8.50 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?

Answer 1

The following equation is correct and is the best.
8.50(c+a)

Answer 2

8.50(c+a)

Explanation:

Here,

Total number of children who bought tickets = c,

Total number of adults who bought tickets = a

Thus, the total number of people = children + adults

= c + a

Now, the cost of ticket for each person = $ 8.50,

So, the total cost of the tickets bought by 'c+a' persons = 8.50(c+a)

Which is the required expression.
