the cost of one kids ticket is $7.8

the cost of one adult ticket is $15.6

Step-by-step explanation:

Let x represent the cost of one kids ticket.

Let y represent the cost of one adult ticket.

Nine kids and three adults are going to the circus. The total cost of the tickets is $117. It means that

9x + 3y = 117 - - - - - - - - - - - - 1

Kid's tickets are on sale for only half the price of adult adult ticket. This means that

x = y/2

y = 2x

Substituting y = 2x into equation 1, it becomes,

9x + 3 × 2x = 117

9x + 6x = 117

15x = 117

x = 117/15 = 7.8

y = 2x = 2 × 7.8

y = 15.6
