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 10
=
60100 x 10
= $6
Total sales of tickets
= 90 u + 6 u
= 96 u
96 u = 7392
1 u = 7392 ÷ 96 = 77
Number of tickets sold that were for adults
= 9 u
= 9 x 77
= 693
