70100 =
710 50% x 370
=
50100 x 370
= 185
370 - 185 = 185
Total number of tickets sold on Tuesday
= 5 u + 185 + 17 u
= 22 u + 185
22 u + 185 = 625
22 u = 625 - 185
22 u = 440
1 u = 440 ÷ 22 = 20
Total number of tickets sold to all the women
= 10 u + 17 u
= 27 u
= 27 x 20
= 540
Amount collected from the sale of concert tickets to all the women
= 540 x 8
= $4320
Answer(s): $4320
