110Price of each adult ticket in percent = 100%
Price of each child ticket in percent
= 100% - 40%
= 60%
Price of each child ticket
= 60% x 20
=
60100 x 20
= $12
Total sales of tickets
= 180 u + 12 u
= 192 u
192 u = 9984
1 u = 9984 ÷ 192 = 52
Number of tickets sold that were for adults
= 9 u
= 9 x 52
= 468
