Total Value |
8 u |
12 u + 120 |
20 u + 120 |
Number of children = 1 u
Number of adults = 1 u + 10
Total amount collected from the sale of the child tickets
= 8 x 1 u
= 8 u
Total amount collected from the sale of the adult tickets
= 12 x (1 u + 10)
= 12 u + 120
The amount collected from the sale of the adult tickets is $1128 more than the amount from the sale of the child tickets.
12 u + 120 = 8 u + 1128
12 u - 8 u = 1128 - 120
4 u = 1008
1 u = 1008 ÷ 4 = 252
Total amount collected from the tickets sold
= 8 u + 12 u + 120
= 20 u + 120
= 20 x 252 + 120
= 5040 + 120
= $5160
Answer(s): $5160
