Fraction of the tickets given free
= 1 -
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 90
=
80100 x 90
= $72
Number of tickets given for free = 3 u
3 u = 120
1 u = 120 ÷ 3 = 40
Total amount collected from the sales of the ticket
= 450 u + 144 u
= 594 u
= 594 x 40
= $23760
Answer(s): $23760
