19= 1 -

218 =
1318 Price of the ticket after discount in percent
= 100% - 10%
= 90%
Price of the ticket at 10% discount
= 90% x 80
=
90100 x 80
= $72
Number of tickets given for free = 13 u
13 u = 520
1 u = 520 ÷ 13 = 40
Total amount collected from the sales of the ticket
= 240 u + 144 u
= 384 u
= 384 x 40
= $15360
Answer(s): $15360
