To watch the high school play, theatre goers must buy a ticket at the door. The cost of an adult ticket is $10.00, and the cost of a student ticket is $7.50. If the number of adult tickets sold is represented by a, and the number of student tickets sold is represented by s, which expression represents the amount of money collected at the door from the ticket sales?

10a+7.5s

Step-by-step explanation: Since the price of an adult ticket(a) is $10 it is logical to say that the total amount of money that will be collected from adult tickets is 10 * a, where a is the amount of adult tickets. Applying the same for student tickets, we finally add these expressions to get 10a+7.5s. Hope this helped you get it!
