15Price of each adult ticket in percent = 100%
Price of each child ticket in percent
= 100% - 40%
= 60%
Price of each child ticket
= 60% x 5
=
60100 x 5
= $3
Total sales of tickets
= 20 u + 3 u
= 23 u
23 u = 1242
1 u = 1242 ÷ 23 = 54
Number of tickets sold that were for children
= 1 u
= 1 x 54
= 54
