Fraction of the tickets given free
= 1 -
115 -
12= 1 -
230 -
1530 =
1330 Price of the ticket after discount in percent
= 100% - 30%
= 70%
Price of the ticket at 30% discount
= 70% x 20
=
70100 x 20
= $14
Number of tickets given for free = 13 u
13 u = 650
1 u = 650 ÷ 13 = 50
Total amount collected from the sales of the ticket
= 40 u + 210 u
= 250 u
= 250 x 50
= $12500
Answer(s): $12500
