Question 862103: Tickets for a play cost $3.00 each for children and $5.00 each for adults. The revenue from a recent performance was $663.00 when 145 tickets were sold. How many adult tickets and how many children's tickets were sold?
Let x= the number of children tickets that were sold
Let y= the number of adult tickets that were sold
I have to find two equations and either use substitution or elimination. I have NO IDEA on this problem. My best guess is the first equation is 5x+y=145 and the second is x+3y=145. Is the $663.00 important? Please help!

This is a cost revenue type problem and an application of a simple linear system. Here is restating and refining your analysis:

child ticket price, 3 dollars per ticket
adult ticket price, 5 dollars per ticket
x = count of child tickets
y = count of adult tickets

ACCOUNT FOR AMOUNT OF TICKETS: highlight%28x%2By=145%29
ACCOUNT FOR TICKET SALES: highlight%283x%2B5y=663%29

Work at understanding that. Once you understand that process and those resulting equations, you should find that solving for x and y is an easy task.
