110Price of each adult ticket in percent = 100%
Price of each child ticket in percent
= 100% - 50%
= 50%
Price of each child ticket
= 50% x 40
=
50100 x 40
= $20
Total sales of tickets
= 360 u + 20 u
= 380 u
380 u = 22800
1 u = 22800 ÷ 380 = 60
Number of tickets sold that were for adults
= 9 u
= 9 x 60
= 540
Answer(s): 540
