Write and solve a system of equations for each situation. Check your answers.
13. Your school sells tickets for its winner concert. Student tickets are $5 and adult tickets are $10. If your school sells 85 tickets and makes $600, how many of each ticket did they sell?
14. A grocery store has small bags of apples for $5 and large bags of apples for $8. If you buy 6 bags and spend $45, how many of each size bag did you buy?

13.
number of adult tickets sold = x
number of student tickets = 85x
solve: 10x + 8(85x) = 600
14. set it up the same way as #13
number of bags of small apples = x
number of bags of large apples = 6x
etc. 
20

x+65

A grocery store has small bags of apples for $5 and large bags of apples for $8. If you
buy 6 bags and spend $45, how many of each size bag did you buy?
