Given the total revenue function, TR = 1400Q − 6Q 2 and the total cost function, TC = 1500 + 80 Q at Q = 100 units (where Q is the amount of output), which one of the following is correct? A. MR > MC B. MC = 80 C. MR < MC D. MR = MC
A and B are true only
\(MR=\frac{dTR}{dQ}=1400-12Q\); at Q = 100, MR = 200. Also \(MC=\frac{dTC}{dQ}=80\). Hence MR > MC and MC = 80: A and B only.

Choose the correct answer from the options given below:
As output expands, LAC curve falls. This is due to:
Given \(TC=Q^3-10Q^2+60Q\) for \(Q>0\), what is the minimum average cost and at what output does this minimum average cost occur?
