Block pricing profit maximization

[ihateecon]

How do I find profit maximizing quantities for a monopolist that wants two different price blocks when the marginal cost is not constant?

e.g. Demand: P(Q)=951-2Q and C(Q)=Q^2+9Q, therefore MC(Q)=2Q+9.

We need more context to the equations you presented. What’s P, Q,C and MC?

This is the stupid notation used by economists. I am not sure what is meant by price blocks. Usually P stands for price, but based on what this student has written, it may stand for quantity demanded.

Q probably means both quantity produced and quantity sold on the assumption that everything produced is sold (an assumption that is seldom true in real life). MC is the derivative of the cost function (M is the stupid way economists indicate a derivative.)

Personally, I am not going to give a bit of help to this student until he follows the read-before-posting instructions and gives us the problem exactly and completely. Why when it says right at the top of the page READ BEFORE POSTING does it never happen?

This is in fact the COMPLETE and EXACT problem and I did READ BEFORE POSTING. If you don't know what block pricing is, clearly you cannot help. No need to be rude.

I figured out the problem before the post was approved and was unable to delete it. Apologies for the anguish my "stupid" econ problem brought you.
