The Total Revenue equation is as follows:
Now, it shall be derived that the Marginal Revenue equation as below;
Now, in order to maximize TR, it shall be equated that MR to 0;
Now, substitute this value of q in the above equation;
Thus, it can be concluded that the total revenue of the firm is maximized at a price rate of a/2 dollars, and at a quantity of a/2b units. Further, it should be observed that when the price elasticity of demand becomes -1, the TR is maximized.

Answer to Problem 8.5P
We can find that the solution from part A was that of a
Explanation of Solution
On comparing, it can be found that the solution derived in part A was that of a Perfectly Competitive market, part B is related to a sales maximizing firm, and solution of part D was related to a monopoly firm.
Moreover, the quantity produced in parts A and B is more than in the parts C and D.
Further, the price charged in parts A, B and C is lower than the price determined in part D.

- Please diagram the revenue and profit situation (which would also include the cost curves) for a producer of a highly elastic (but not perfectly elastic) good of your choice (a restaurant, boutique clothing store, etc.). Under what circumstances would it make sense for them to raise their price? While profit maximization is the main goal for most firms (and one which you should be able to represent on a diagram), you may wish to consider alternative goals depending upon the business you have chosen. Note:- Do not provide handwritten solution. Maintain accuracy and quality in your answer. Take care of plagiarism. Answer completely. You will get up vote for sure.arrow_forwardBeta Industries manufactures floppy disks that consumers perceive as identical to those produced by numerous other manufacturers.
