110Price of each adult ticket in percent = 100%
Price of each child ticket in percent
= 100% - 30%
= 70%
Price of each child ticket
= 70% x 40
=
70100 x 40
= $28
Total sales of tickets
= 360 u + 28 u
= 388 u
388 u = 21728
1 u = 21728 ÷ 388 = 56
Number of tickets sold that were for children
= 1 u
= 1 x 56
= 56
Answer(s): 56
