8 u |
11 u + 198 |
19 u + 198 |
Number of children = 1 u
Number of adults = 1 u + 18
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
= 11 x (1 u + 18)
= 11 u + 198
The amount collected from the sale of the child tickets is $612 less than the amount from the sale of the adult tickets.
11 u + 198 = 8 u + 612
11 u - 8 u = 612 - 198
3 u = 414
1 u = 414 ÷ 3 = 138
Total amount collected from the tickets sold
= 8 u + 11 u + 198
= 19 u + 198
= 19 x 138 + 198
= 2622 + 198
= $2820
Answer(s): $2820
