25Price of each adult ticket in percent = 100%
Price of each child ticket in percent
= 100% - 25%
= 75%
Price of each child ticket
= 75% x 20
=
75100 x 20
= $15
Total sales of tickets
= 60 u + 30 u
= 90 u
90 u = 6390
1 u = 6390 ÷ 90 = 71
Number of tickets sold that were for children
= 2 u
= 2 x 71
= 142
