15Price of each adult ticket in percent = 100%
Price of each child ticket in percent
= 100% - 25%
= 75%
Price of each child ticket
= 75% x 40
=
75100 x 40
= $30
Total sales of tickets
= 160 u + 30 u
= 190 u
190 u = 11590
1 u = 11590 ÷ 190 = 61
Number of tickets sold that were for adults
= 4 u
= 4 x 61
= 244
