Final answer:
The total amount of money collected at the door from ticket sales for a varsity basketball game, with adult tickets costing $3.00 and student tickets costing $1.50, is represented by the expression 3.00a + 1.50s, where a is the number of adult tickets and s is the number of student tickets sold.
Step-by-step explanation:
To calculate the amount of money collected at the door from the ticket sales at a varsity basketball game, we need to use the given cost of each type of ticket and the number of tickets sold. The cost of an adult ticket is $3.00, and the cost for a student ticket is $1.50. If the number of adult tickets sold is represented by a and the number of student tickets sold by s, the total money collected at the door can be represented by the following expression:
3.00a + 1.50s
The expression that represents the amount of money collected at the door from the ticket sales is (3.00a + 1.50s).
This expression consists of two parts; the first part 3.00a represents the total revenue from adult tickets, and the second part 1.50s represents the total revenue from student tickets. By adding these two parts together, we get the total amount of money collected from ticket sales.
