310Price of each adult ticket in percent = 100%
Price of each child ticket in percent
= 100% - 50%
= 50%
Price of each child ticket
= 50% x 10
=
50100 x 10
= $5
Total sales of tickets
= 70 u + 15 u
= 85 u
85 u = 6630
1 u = 6630 ÷ 85 = 78
Number of tickets sold that were for adults
= 7 u
= 7 x 78
= 546
