Answer: At x = 2200 level of production, it will get maximum revenue.
Step-by-step explanation:
Since we have given that
p = 55-0.0125x
and Revenue function is given by

We will take the first derivative of it.

Now,we will find the critical points :

and R''(x)=-0.025<0, so it will get maximum revenue.
Hence, At x = 2200 level of production, it will get maximum revenue.
