Answer: 50x=15000, and  x>0


Step-by-step explanation:

Let the number of adult tickets be x .

then the number of children's tickets =3x

Since the ballpark charges $20 for each adult ticket and $10 for each child's ticket.

Therefore total sales on Wednesday=20x+10(3x)

=20x+30x=50x

Since the ballpark made a total of $15,000 from ticket sales at Wednesday's game.

⇒The required equation must be 50x=15000, and  x>0
