  (i) Because 132 tickets were sold in total

  (ii)   because the total of $ obtained by sales was 931.20.

We must clear x. Then we substitute (i) in (ii)

60 tickets for children were sold

60 child tickets

Step-by-step explanation:

Let x denote the number of child tickets sold and y the number of adult tickets sold. The problem involves solving the following system of linear equations; x+y=132 and 5.2x+8.6y=931.2. Using technology to solve this simultaneous equation yields; x= 60
