Five kids and two adults are going to the circus. Kid's tickets are on sale for only half of the adult tickets. The total cost is $50. How much is one kids ticket? How much is one adult ticket?

Answer 1

kid's ticket ---- $ x
adult's ticked --- $ 2x
5x + 2(2x) = 50
9x = 50
x = 5.5555..
2x = 11.1111

so a children ticket is $5.56 and an adult ticket is $11.11

check: 2 adults + 5 kids
= 2(11.11) + 5(5.56)
= 50.02
(I would have designed the question so the price comes out exact to the penny)
