70100 =
710 50% x 660
=
50100 x 660
= 330
660 - 330 = 330
Total number of tickets sold on Sunday
= 5 u + 330 + 17 u
= 22 u + 330
22 u + 330 = 1276
22 u = 1276 - 330
22 u = 946
1 u = 946 ÷ 22 = 43
Total number of tickets sold to all the men
= 10 u + 17 u
= 27 u
= 27 x 43
= 1161
Amount collected from the sale of concert tickets to all the men
= 1161 x 20
= $23220
Answer(s): $23220
