9 u |
14 u + 294 |
23 u + 294 |
Number of children = 1 u
Number of adults = 1 u + 21
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
= 14 x (1 u + 21)
= 14 u + 294
The amount collected from the sale of the adult tickets is $1144 more than the amount from the sale of the child tickets.
14 u + 294 = 9 u + 1144
14 u - 9 u = 1144 - 294
5 u = 850
1 u = 850 ÷ 5 = 170
Total amount collected from the tickets sold
= 9 u + 14 u + 294
= 23 u + 294
= 23 x 170 + 294
= 3910 + 294
= $4204
Answer(s): $4204
