A theater company charges $4.50 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? 4.5(c + a) 4.5c + a c + 4.5a 9(c + a)
4.5(c+a) because the price of each ticket is $4.50 no matter how old you are so you add both of them and then multiply that sum by the price of each ticket which is 4.5 so the answer is 4.5(c+a).
