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:)
