1324 Price of the ticket after discount in percent
= 100% - 20%
= 80%
Price of the ticket at 20% discount
= 80% x 20
=
80100 x 20
= $16
Number of tickets given for free = 13 u
13 u = 1170
1 u = 1170 ÷ 13 = 90
Total amount collected from the sales of the ticket
= 60 u + 128 u
= 188 u
= 188 x 90
= $16920
