70100 =
710 40% x 150
=
40100 x 150
= 60
150 - 60 = 90
Total number of tickets sold on Wednesday
= 6 u + 90 + 17 u
= 23 u + 90
23 u + 90 = 964
23 u = 964 - 90
23 u = 874
1 u = 874 ÷ 23 = 38
Total number of tickets sold for the two days
= (10 u + 150) + 10 u + (6 u + 90) + 17 u
= 43 u + 240
= 43 x 38 + 240
= 1874
Amount collected from the sale of concert tickets for the two days
= 1874 x 15
= $28110
Answer(s): $28110
