Suppose that there are two types of tickets to a show: advanced and same day.  The combined cost of one advance ticket and one same day ticket is $45.  For one performance, 30 advance tickets and 40 same day tickets were sold.  The total amount paid for the tickets was $1500.  What was the price of each kind of ticket?

Thank you for the opportunity to help you with your question!

advanced ticket=x

same day ticket=y

x+y=45-----------(1)

30x+40y=1500-------------(2)

form (1)

x=45-y

substitute in equation(2)

30(45-y)+40y=1500

solve for y

1350-30y+40y=1500

10y=150

y=$15

so

x=45-15

x=$30

price of advanced ticket=$30

price of same day ticket=$15

Please let me know if you need any clarification. I'm always happy to answer your questions.
