child tickets sold.​

Answer:

The number of adult tickets sold was 300 and that of child's ticket sold is 900.

Step-by-step explanation:

Let us assume that the ticket sales at Wednesday's game are x number adult and y number child's tickets.

Therefore, as per given conditions, we can write, y = 3x .......... (1)

Again, each adult ticket cost $20 and each child's ticket costs $10 and there was a $15000 ticket sale.

So, 20x + 10y = 15000

⇒ 2x + y = 1500 ......... (2)

Now, solving equations (1) and (2) we get,

2x + 3x = 1500

⇒ 5x = 1500

⇒ x = 300 and y = 3x = 900

Therefore, the number of adult tickets sold was 300 and that of child's ticket sold is 900. (Answer)
