310Price 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
= 140 u + 36 u
= 176 u
176 u = 14256
1 u = 14256 ÷ 176 = 81
Number of tickets sold that were for children
= 3 u
= 3 x 81
= 243
