10% =
10100 =
110Price 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
= 180 u + 15 u
= 195 u
195 u = 15405
1 u = 15405 ÷ 195 = 79
Number of tickets sold that were for children
= 1 u
= 1 x 79
= 79
Answer(s): 79
