hi can someone help me with this problem. i cant figure out which equation to use. thanks
a full-price ticket for a college basketball game costs $2.50, and a student ticket costs $1.75. if 585 tickets were sold , and the total reciepts were $1,217,25, how many tickets were student tickets?
Let x = number of full price tickets and y = number of student tickets.
x + y = 585, then x = 585 - y
2.5x + 1.75y = 1217.25
Substitute 585 - y for x in second equation and solve for y.
I hope this helps. Thanks for asking.
