Question 77478: Please help, I began solving letter see, but I'm not sure if it is correct.
In most businesses, increasing prices of products can negatively impact the number of customers. A bus company in a small town has an average number of riders of 800 per day. The bus company charges $2.25 for a ride. They conducted a survey of their customers and found that they will lose approximately 40 customers per day for each $.25 increase in fare.
a. Let the number of riders be a function of the fare charged. Graph the function, identify the graph of the function, and find the slope of the graph.
b. The bus company determined that even if they set the price very low, there are a maximum number of riders permitted each day. If the price is $0 (free), how many riders are permitted each day?
c. If the bus company sets the price too high, no one will be willing to ride the bus. Beginning at what ticket price will no one be willing to ride the bus?

Question 77459: Ok stan h. you go this..
-(6x-24+3x^2)/(5-26x+ 5x^2)
=(3^2+6x-24)/(5x^2-26x+5)
=3(x^2+2x-12)/(5x^2-25x-x+5)
=3(x^2+2x-12)/(5x(x-5)-(x-5))
=3(x^2+2x-12)/(x-5)(5x-1)
But what would the x equal to??

Answer 55556 by stanbon(7053) on 2007-04-08 11:12:48 (Show Source):

-(6x-24+3x^2)/(5-26x+ 5x^2)
=(3^2+6x-24)/(5x^2-26x+5)
=3(x^2+2x-12)/(5x^2-25x-x+5)
=3(x^2+2x-12)/(5x(x-5)-(x-5))
=3(x^2+2x-12)/(x-5)(5x-1)

I am not sure how to draw the graph to show what it looks like so I will try to explain it. The line comes up from the bottom of quadrant 3 and it goes to the right of (-1,-1)and continues up to (0,2)it then curves down thru (1,0)to (2,-2)and then curves up to just left of (3,0)and keeps going upward.
