70100 =
710 20% x 440
=
20100 x 440
= 88
440 - 88 = 352
Total number of tickets sold on Tuesday
= 8 u + 352 + 17 u
= 25 u + 352
25 u + 352 = 677
25 u = 677 - 352
25 u = 325
1 u = 325 ÷ 25 = 13
Total number of tickets sold to all the men
= 10 u + 17 u
= 27 u
= 27 x 13
= 351
Amount collected from the sale of concert tickets to all the men
= 351 x 5
= $1755
Answer(s): $1755
