25Price of each adult ticket in percent = 100%
Price of each child ticket in percent
= 100% - 20%
= 80%
Price of each child ticket
= 80% x 10
=
80100 x 10
= $8
Total sales of tickets
= 30 u + 16 u
= 46 u
46 u = 4278
1 u = 4278 ÷ 46 = 93
Number of tickets sold that were for adults
= 3 u
= 3 x 93
= 279
