15Price of each adult ticket in percent = 100%
Price of each child ticket in percent
= 100% - 20%
= 80%
Price of each child ticket
= 80% x 5
=
80100 x 5
= $4
Total sales of tickets
= 20 u + 4 u
= 24 u
24 u = 2400
1 u = 2400 ÷ 24 = 100
Number of tickets sold that were for adults
= 4 u
= 4 x 100
= 400
