718 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 = 7 u
7 u = 490
1 u = 490 ÷ 7 = 70
Total amount collected from the sales of the ticket
= 100 u + 84 u
= 184 u
= 184 x 70
= $12880
Answer(s): $12880
