Question 163022
Let x be the number of adult tickets sold.
Then the number of children ticket sold is 505 - x.
The revenue from selling adult tickets is 6x.
The revenue from selling adult tickets is 3(505 - x).
As the total revenue is $1997, we have
6x + 3(505 - x) = 1997
Solving the equation for x, we have
6x + 1515 - 3x = 1997
3x = 482
x = 160.66
I think one of the given numbers must be wrong, as the solution should be an integer.
