You can  put this solution on YOUR website!  A music festival usually attracts 500 people at a cost of $12/person. For every $1 rise in the admission price, 25 less people attend the festival. If y is the total amount of takings and x is the number of $1 increases, find the function which gives y in terms of x.  
------ 
Original condition revenue = 500*12 = $6000 
---- 
Changing revenue when price is raised "x" dollars = (12+x)(500-25x) 
----- 
Ans:: y = (12+x)(500-25x)
