30% =
30100 =
310Price 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
= 140 u + 45 u
= 185 u
185 u = 15725
1 u = 15725 ÷ 185 = 85
Number of tickets sold that were for adults
= 7 u
= 7 x 85
= 595
Answer(s): 595
