Quentin buys 12 tickets for a group of adults and children for a total of $100. Adult tickets are $10 each and child tickets are $5 each. How many of each ticket did Quentin buy?
+134 you can set up some equations for this one:
adult tickets = a
child tickets = c
a+c = 12
10a+5c = 100
a = 12 - c
10(12 - c) + 5c = 100
120 - 10c + 5c = 100
120 - 5c = 100
-5c = -20
c = 4
a = 12 - 4
a = 8
so, Quentin bought 4 child tickets and 8 adult tickets.
hopefully you can follow what i did with the equations above! please correct me if i am wrong:)
