10 u |
18 u + 450 |
28 u + 450 |
Number of children = 1 u
Number of adults = 1 u + 25
Total amount collected from the sale of the child tickets
= 10 x 1 u
= 10 u
Total amount collected from the sale of the adult tickets
= 18 x (1 u + 25)
= 18 u + 450
The amount collected from the sale of the adult tickets is $2770 more than the amount from the sale of the child tickets.
18 u + 450 = 10 u + 2770
18 u - 10 u = 2770 - 450
8 u = 2320
1 u = 2320 ÷ 8 = 290
Total amount collected from the tickets sold
= 10 u + 18 u + 450
= 28 u + 450
= 28 x 290 + 450
= 8120 + 450
= $8570
Answer(s): $8570
