<PRE><B>Question 600437</B>
Assume the no.of adults entering on the given day to be x
Then the number of children entering would be 2300-x and the monies collected from the adults and children will be $ 5x and 2(2300-x) respectively.
Since total collection for the day is $ 5100 

we have the equation  5x + 2(2300-x) = 5100 which we can solve for x giving the no. of adults entering on the day 


Alternatively you could
