15Price of each adult ticket in percent = 100%
Price of each child ticket in percent
= 100% - 20%
= 80%
Price of each child ticket
= 80% x 30
=
80100 x 30
= $24
Total sales of tickets
= 120 u + 24 u
= 144 u
144 u = 11088
1 u = 11088 ÷ 144 = 77
Number of tickets sold that were for children
= 1 u
= 1 x 77
= 77
Answer(s): 77
