70100 =
710 50% x 740
=
50100 x 740
= 370
740 - 370 = 370
Total number of tickets sold on Friday
= 5 u + 370 + 17 u
= 22 u + 370
22 u + 370 = 568
22 u = 568 - 370
22 u = 198
1 u = 198 ÷ 22 = 9
Total number of tickets sold to all the men
= 10 u + 17 u
= 27 u
= 27 x 9
= 243
Amount collected from the sale of concert tickets to all the men
= 243 x 20
= $4860
Answer(s): $4860
