Ответ:
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
