A theater company charges $5.50 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?
The theater charges $5.5 per ticket per person of any age group. Your expression would not have $5.5c or $5.5a as they have a price for only one variable. Your expression would be 5.5(a+c). Your first option is the correct one.
