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? A. 7.50as B. 7.50(a + s) C. (10.00a)(7.50s) D. 10.00a + 7.50s

Answer 1

Answer: Option 'D' is correct.

Step-by-step explanation:

Let the number of adult tickets sold be 'a'.

Let the number of students tickets sold be 's'.

Cost of an adult ticket = $10.00

Cost of a student ticket = $7.50

According to question, it becomes,

$10.00a+7.50s$

Hence, option 'D' is correct.

Answer 2

The expression that represents the amount of money collected at the door from the ticket sales is $10a + $7.50s

The total amount collected at the door is the sum of the total cost of adult tickets and children tickets

Total cost of adults ticket = cost per ticket x total number of adults tickets sold

$10 x a = $10a

Total cost of children's ticket = cost per ticket x total number of children tickets sold

$7.50 x s = $7.50s

The total amount collected at the door  = $10a + $7.50s
