Del's and Rodney's are two plumbing services in a gentrifying area of South East
London. Within the area they service, the two firms operate as a duopoly and
together serve one hundred percent of the available local market. One of their key
lines of business is visiting customer's homes to install a new shower rail. A student
project has been investigating the local plumbing business and has estimated the
following information for Del's and Rodney's:
Total demand for new shower rails per week is given by
P = 200 - 4Q
Where Q is total market demand and can be divided between Del's (qd) and
Rodney's (qr) such that
Q = qd + qr
Assuming that the marginal cost of serving an extra customer is £40 for each, and
that marginal revenue for Del is given by
MRd
2008qd - 4qr
And marginal revenue for Rodney is given by
MRr
Then
2008qr - 4qd

- JYour business has the capacity to produce up to 5 units/week. The table & graph below show average cost (AC) for different weekly production levels. Your objective is to maximize profit each week. Average Cost 22 20 AC 18 1 20 14 2 15 12 3 12 10 1 2 4 4 13 Quantity 15 Your product sells in the market for $21/unit, and you can sell as many units at that price as you can bring to market. You know from your economics training that deciding how much to produce should rely on marginal concepts like marginal cost (MC). So, based on the AC table above, create a table that shows the MC of each unit. (Assume that there are no fixed costs, so total costs are zero if Q=0.) Based on MC for each unit, determine the profit-maximizing quantity to produce and sell. BRIEFLY explain your answer. (Your answer needs to be based on MC and being able to sell each unit for $21.)

- Sally runs a vegetable stand. The following table shows two points on the demand curve for the heirloom tomatoes she sells: Price $3.50 $2.25 Quantity demanded per week 150,000 250,000 Sally's marginal revenue from lowering the price of tomatoes from $3.50 to $2.25 is $ 0.375. (Enter your response rounded to two decimal places.) Lowering the price from $3.50 to $2.25 results in an output effect of $ and a price effect of $.

- Calculate Iyana's marginal revenue and marginal cost for the first seven rompers they produce, and plot them on the following graph. Use the blue points (circle symbol) to plot marginal revenue and the orange points (square symbol) to plot marginal cost at each quantity.

Iyana's profit is maximized when they produce a total of is $ , an amount rompers. At this quantity, the marginal cost of the final romper they produce than the price received for each romper they sell. At this point, the marginal cost of producing one more romper (the first romper beyond the profit maximizing quantity) is $ , an amount than the price received for each romper they sell. Therefore, Iyana's profit-maximizing quantity occurs at the point of intersection between the Because Iyana is a price taker, the previous condition is equivalent to curves.arrow_forwardSuppose Becky runs a small business that manufactures shirts.
