h. Produce a graph of total revenue and marginal revenue. Graph total revenue for quantities up to 2,500 and put the marginal revenue graph on separate axes, and graph marginal revenue for quantities up to 2,500 also. i. What level of sales will maximize the company’s total revenues? What price does the company have to charge for X for that level of sales result?

Homework Answers

Answer #1

TR = PQ = PXQX.

Find inverse demand function PX = 2460/40 – QX/40

PX = 61.5 – 0.025QX

TR = (61.5 – 0.025QX)QX

MR = 61.5 – 0.05QX

h. Total revenue and marginal revenue are plotted below for QX up to 2,500.

i. The level of sales that will maximize the company’s total revenues is the one that makes marginal revenue 0

MR = 0

61.5 – 0.05QX = 0

QX = 1230

Hence the quantity 1230 will maximize revenue.

Price = 61.5 – 0.025*1230 = 30.75 is the required price.

Required table

Q Total revenue Marginal revenue
0 0 61.5
500 24500 36.5
1000 36500 11.5
1500 36000 -13.5
2000 23000 -38.5
2500 -2500 -63.5

* City Computers has determined that the price-demand and revenue functions are given by p(x) = 2,000 – 6x and R(x) = x(2,000 – 6x), where x is in thousands of computers. This means that R(x) is measured in thousands of dollars. Additionally we know: * The fixed cost is $100,000. * The variable cost is $250 per computer. This means that the cost function is given by C(x) = 100 + 250x. Also again C(x) is measured in thousands...

1). The market demand function for a good is given by Q = D(p) = 800 − 50p. For each firm that produces the good the total cost function is TC(Q) = 4Q+( Q2/2) . Recall that this means that the marginal cost is MC(Q) = 4 + Q. Assume that firms are price takers. (a) What is the efficient scale of production and the minimum of average cost for each firm? Hint: Graph the average cost curve first. (b)...
