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 20
=
50100 x 20
= $10
Total sales of tickets
= 140 u + 30 u
= 170 u
170 u = 16320
1 u = 16320 ÷ 170 = 96
Number of tickets sold that were for adults
= 7 u
= 7 x 96
= 672
Answer(s): 672
