9 u |
13 u + 221 |
22 u + 221 |
Number of children = 1 u
Number of adults = 1 u + 17
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
= 13 x (1 u + 17)
= 13 u + 221
The amount collected from the sale of the child tickets is $669 less than the amount from the sale of the adult tickets.
13 u + 221 = 9 u + 669
13 u - 9 u = 669 - 221
4 u = 448
1 u = 448 ÷ 4 = 112
Total amount collected from the tickets sold
= 9 u + 13 u + 221
= 22 u + 221
= 22 x 112 + 221
= 2464 + 221
= $2685
Answer(s): $2685
