25Price of each adult ticket in percent = 100%
Price of each child ticket in percent
= 100% - 50%
= 50%
Price of each child ticket
= 50% x 10
=
50100 x 10
= $5
Total sales of tickets
= 30 u + 10 u
= 40 u
40 u = 3120
1 u = 3120 ÷ 40 = 78
Number of tickets sold that were for adults
= 3 u
= 3 x 78
= 234
