the profit P for a company is P=100xe-x/400 where x is in sales. use the method of differentials to approximate the change in profit as the production increases from x=115 to x=120 units



Expert Answer

Step 1

As a first step let's find the derivative of P as shown on whiteboard and establish the relationship between differentials dP and dx.

Please see the whiteboard. 

Step 2

As a second step, we need to calculate the P', dx and then dP.

As the production increases fro...
