70100 =
710 20% x 370
=
20100 x 370
= 74
370 - 74 = 296
Total number of tickets sold on Saturday
= 8 u + 296 + 17 u
= 25 u + 296
25 u + 296 = 521
25 u = 521 - 296
25 u = 225
1 u = 225 ÷ 25 = 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 8
= $1944
Answer(s): $1944
