Fraction of the tickets given free

735 =
1335 Price of the ticket after discount in percent
= 100% - 20%
= 80%
Price of the ticket at 20% discount
= 80% x 15
=
80100 x 15
= $12
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
= 225 u + 84 u
= 309 u
= 309 x 90
= $27810
Answer(s): $27810
