110Price of each adult ticket in percent = 100%
Price of each child ticket in percent
= 100% - 20%
= 80%
Price of each child ticket
= 80% x 25
=
80100 x 25
= $20
Total sales of tickets
= 225 u + 20 u
= 245 u
245 u = 13720
1 u = 13720 ÷ 245 = 56
Number of tickets sold that were for children
= 1 u
= 1 x 56
= 56
Answer(s): 56
