12 -
15= 1 -
510 -
210 =
310 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 = 3 u
3 u = 240
1 u = 240 ÷ 3 = 80
Total amount collected from the sales of the ticket
= 100 u + 32 u
= 132 u
= 132 x 80
= $10560
Answer(s): $10560
