Answer:</h3>
- 1650 Adult tickets
- 4950 children's tickets
<h3>
Step-by-step explanation:</h3>
<em>Using numerical reasoning</em>
Sale of 6600 children's tickets would provide revenue of ...
... 6600×$26 = $171,600
Revenue was actually $188,100 -171,600 = $16,500 more than that. Each adult ticket sold instead of a children's ticket increases revenue by $36 -26 = $10, so there were $16,500/$10 = 1650 adult ticket sold.
The number of children's tickets was then 6600 -1650 = 4950.
_____
<em>Using an equation</em>
Let "a" represent the number of adult tickets sold. Then the number of children's tickets is (6600-a) and the total revenue is ...
... 36a +26(6600 -a) = 188,100
... 10a = (188,100 -171,600) . . . . . . . collect terms, subtract 26·6600
... 16,500/10 = a = 1650 . . . . . . . . . divide by the coefficient of "a"
... (6600 -a) = 6600 -1650 = 4950 . . . . . childrens's tickets sold.
There were 1650 adult and 4950 children's tickets sold.
