70100 =
710 20% x 390
=
20100 x 390
= 78
390 - 78 = 312
Total number of tickets sold on Saturday
= 8 u + 312 + 17 u
= 25 u + 312
25 u + 312 = 1037
25 u = 1037 - 312
25 u = 725
1 u = 725 ÷ 25 = 29
Total number of tickets sold to all the men
= 10 u + 17 u
= 27 u
= 27 x 29
= 783
Amount collected from the sale of concert tickets to all the men
= 783 x 13
= $10179
Answer(s): $10179
