Chapter 10, Problem 10.36P

High-low method and regression analysis. Market Thyme, a cooperative of organic family-owned farms, has recently started a fresh produce club to provide support to the group’s member farms and to promote the benefits of eating organic, locally produced food. Families pay a seasonal membership fee of $100 and place their orders a week in advance for a price of $40 per order. In turn, Market Thyme delivers fresh-picked seasonal local produce to several neighborhood distribution points. Five hundred families joined the club for the first season, but the number of orders varied from week to week.

Tom Diehl has run the produce club for the first season. Tom is now a farmer but remembers a few things about cost analysis from college. In planning for next year, he wants to know how many orders will be needed each week for the club to break even, but first he must estimate the club’s fixed and variable costs. He has collected the following data over the club’s first season of operation:

Week Number of Orders per Week Weekly Total Costs
1 415 $26,900
2 435 27,200
3 285 24,700
4 325 25,200
5 450 27,995
6 360 25,900
7 420 27,000
8 460 28,315
9 380 26,425
10 350 25,750
  1. 1. Plot the relationship between number of orders per week and weekly total costs.
  2. 2. Estimate the cost equation using the high-low method, and draw this line on your graph.
  3. 3. Tom uses his computer to calculate the following regression formula:

   Weekly total costs = $ 18 , 791 + ( $ 19.97 × Number of orders per weekly )

Draw the regression line on your graph. Use your graph to evaluate the regression line using the criteria of economic plausibility, goodness of fit, and significance of the independent variable. Is the cost function estimated using the high-low method a close approximation of the cost function estimated using the regression method? Explain briefly.

  1. 4. Did Market Thyme break even this season? Remember that each of the families paid a seasonal membership fee of $100.
  2. 5. Assume that 500 families join the club next year and that prices and costs do not change. How many orders, on average, must Market Thyme receive each of 10 weeks next season to break even?

Consider the following hypothetical sales scenario. A large community college buys and takes delivery of 50 iMac computers from a local Apple store.  The invoiced price is $2,800 per unit and includes hardware, software essential to the functionality of the hardware, third-party software including Microsoft Office for Mac and Adobe Creative Suite, and two years of tech service and support.  Apple uses vendor-specific objective evidence to determine unit prices of $2,500 and $300 for hardware and the essential software, respectively.  The third-party software typically retails for $500 (but Apple purchases it at a 50% discount) and equivalent service and support contracts are $100 per year.  The customer (the community college) can opt to purchase subsequent essential software and OS upgrades.  Indicate how Apple should record gross revenue for the transaction at the time the customer takes delivery of the computers.  Your response should include specific dollar amounts.
MARKETING: ​Kroger, the​ country's leading​ grocery-only chain, added a line of private label organic and natural foods call Simple Truth to its stores. If​ you've priced organic​ foods, you know they are more expensive. For​ example, a dozen conventionally farmed​ Grade-A eggs at Kroger costs consumers ​$1.501.50​, whereas Simple Truth eggs are priced at ​$3.453.45 per dozen. One study found​ that, overall, the average price of organic foods is 85 percent more than that of conventional foods.​ However, if prices get too​ high, consumers will not purchase the organic options. One element of sustainability is organic​ farming, which costs much more than conventional​ farming, and those higher costs are passed on to consumers. Suppose that a conventional egg​ farmer's average fixed costs per year for​ conventionally-farmed eggs are​ $1 million per​ year, but an organic egg​ farmer's fixed costs are fourfour times that amount. Further assume that the organic​ farmer's variable costs of…
Dairyplus processes organic milk into plain yogurt.   Dairyplus sells plain yogurt to​ hospitals, nursing​ homes, and restaurants in​ bulk, one-gallon containers. Each​ batch, processed at a cost of $830​, yields 300 gallons of plain yogurt. Dairyplus sells the​ one-gallon tubs for ​$8 ​each, and spends ​$0.14 for each plastic tub. Dairyplus has recently begun to reconsider its strategy. Dairyplus wonders if it would be more profitable to sell​ individual-size portions of fruited organic yogurt at local food stores. Dairyplus could further process each batch of plain yogurt into 6,400 individual portions​ (3/4 cup​ each) of fruited yogurt. A recent market analysis indicates that demand for the product exists. Dairyplus would sell each individual portion for ​$0.58. Packaging would cost $0.05 per​ portion, and fruit would cost $0.09 per portion. Fixed costs would not change.     Should Dairyplus continue to sell only the​ gallon-size plain yogurt​ (sell as​ is) or convert the plain…
