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 12
=
75100 x 12
= $9
Total sales of tickets
= 84 u + 27 u
= 111 u
111 u = 9768
1 u = 9768 ÷ 111 = 88
Number of tickets sold that were for adults
= 7 u
= 7 x 88
= 616
