Fraction of the tickets given free

12= 1 -
430 -
1530 =
1130 Price of the ticket after discount in percent
= 100% - 20%
= 80%
Price of the ticket at 20% discount
= 80% x 40
=
80100 x 40
= $32
Number of tickets given for free = 11 u
11 u = 330
1 u = 330 ÷ 11 = 30
Total amount collected from the sales of the ticket
= 160 u + 480 u
= 640 u
= 640 x 30
= $19200
Answer(s): $19200
