Suppose on a highway, there is a Dhaba. Name it by Dhaba A.
You are also planning to set up a new Dhaba. Where will you set up your Dhaba?
Model this as a Mathematical Problem. This is an interesting and creative part of the BusinessoMath-man in you.
You have to assume something for Mathematical simplicity to model a real life phenomenon via math.
Assumptions:
Observe that the assumptions are valid and are actually followed in real life. Just sit and think for some time placing yourself in that position.
The Explicit Mathematical Problem
Profit Calculation of your Dhaba B
Now based on the lengths of the roads above and the assumptions made, we have to calculate the profit of Dhaba B.
So the profit made by B = c.R , where R is the length of the road on which B has monopoly. Here, as shown R = \c.( x + \frac{|d-x|}{2}\).
We have assumed in this case that \(0 \leq x \leq d\) by the diagram.
So, the profit for the Dhaba B is c.\(\frac{d+x}{2}\) .
Hence as \(0 \leq x \leq d\), the profit is maximized if x = d.
Exercise: Show that the profit of Dhaba B as a function of x is c.(\( 1 - \frac{d+x}{2}\)) if \(d \leq x \leq 1\) .
Also, observe that in this case the profit is maximized at x = d.
Exercise: Calculate the maximum profit in both cases. Do you observe something fishy? What steps and what arguments will you give to understand the fishiness?
