- Consider a small landscaping company run by Mr. Viemeister. He is considering increasing his firm’s capacity. If he adds one more worker, the firm’s total monthly revenue will increase from $50,000 to $62,000. If he adds one more tractor, monthly revenue will increase from $50,000 to $58,000. Each additional worker costs $4,000 per month, while an additional tractor would also cost $4,000 per month. Instructions: Enter your answers as a whole number. a. What is the marginal revenue product of labor? $ The marginal revenue product of capital? $ b. What is the ratio of the marginal revenue product of labor to the price of labor (MRPL/PL)? : What is the ratio of the marginal revenue product of capital to the price of capital (MRPC/PC)? :arrow_forward①The total cost for producing x items is given by 12x + 3735.

The Supplier is willing to sell 5 items if the price is $70 per item and 12 items if the price is $140 per item.

If Firm A has constant marginal cost, and input prices double to 2r and 2w, how much will it cost to produce q 6 units of output (what is c(6, 2r, 2w))? (HINT: First calculate the marginal cost for c(q, r, w), then calculate c(6, r, w), and then calculate c(6, 2r, 2w)) = Firm A has cost function c(q, r, w). At output q = cost is c(5,r, q) ○ c(6, 2r, 2w) ○ c(6, 2r, 2w) = 90 ○ c(6, 2r, 2w) = 150 c(6, 2r, 2w) O c(6, 2r, 2w) = 180 - = - 75 160 = 60, and at output q -arrow_forward
- 8. A commodity has price demand function p(x)= 11800 - .01x and each unit costs 1000 and the overhead is 5000. a) what is the revenue function, cost function and profit function ? b) what price should be charged to maximize profits? c) what is the marginal profit for x=400 ? Explain what this marginal profit number means.arrow_forwardProve it! 2. If the demand function for products A and B is in the order Pa = 36 - 3Qa and Pb = 40 - 5Qb and the common cost function is TC = Qa' + 2QaQb + 3Qb². With the above information, then calculate: a. Production values A and B at the maximum or minimum profit levels. b. The maximum or minimum profit value Did the profit reach its maximum or minimum value?

Further, select whether the firm will choose to produce, shut down, or be indifferent between the two in the short run. (Assume that when price exactly equals average variable cost, the firm is indifferent between producing zero jumpsuits and the profit-maximizing quantity of jumpsuits.) Lastly, determine whether the firm will earn a profit, incur a loss, or break even at each price. 72 80 Produce or Shut Down? Profit or Loss?arrow_forward
