9 u |
11 u + 121 |
20 u + 121 |
Number of children = 1 u
Number of adults = 1 u + 11
Total amount collected from the sale of the child tickets
= 9 x 1 u
= 9 u
Total amount collected from the sale of the adult tickets
= 11 x (1 u + 11)
= 11 u + 121
The amount collected from the sale of the child tickets is $543 less than the amount from the sale of the adult tickets.
11 u + 121 = 9 u + 543
11 u - 9 u = 543 - 121
2 u = 422
1 u = 422 ÷ 2 = 211
Total amount collected from the tickets sold
= 9 u + 11 u + 121
= 20 u + 121
= 20 x 211 + 121
= 4220 + 121
= $4341
Answer(s): $4341
