Chapter 4, Problem 21P
A manager is trying to decide whether to buy one machine or two. If only one machine is purchased and demand proves to be excessive, the second machine can be purchased later. Some sales would be lost, however, because the lead time for delivery of this type of machine is 6 months. In addition, the cost per machine will be lower if both machines are purchased at the same time. The probability of low demand is estimated to be 0.30 and that of high demand to be 0.70. The after tax
If one machine is purchased and demand is low, the NPV is $120,000. If demand is high, the manager has three options: (1) doing nothing, which has an NPV of $120,000; (2) subcontracting, with an NPV of $140,000; and (3) buying the second machine, with an NPV of $130,000.

A manager is trying to decide to buy one machine or two. If only one is purchased and demand proves to be excessive, the second machine can be purchased later. Some sales will be lost, however, because the lead time for producing this type of machine is six months. In addition, the cost per machine will be lower if both are purchased at the same time. The probability of low demand is estimated to be 0.20. The after-tax net present value of the benefits from purchasing the two machines together is $90,000 if demand is low and $180,000 if demand is high.
If one machine is purchased and demand is low, the net present value is $120,000. If demand is high, the manager has three options. Doing nothing has a net present value of $120,000; subcontracting, $160,000; and buying the second machine, $140,000.

- A manager must decide how many machines of a certain type to buy. The machines will be used to manufacture a new gear for which there is increased demand. The manager has narrowed the decision to two alternatives: buy one machine or buy two. If only one machine is purchased and demand is more than it can handle, a second machine can be purchased at a later time. However, the cost per machine would be lower if the two machines were purchased at the same time. The estimated probability of low demand is .30, and the estimated probability of high demand is .70. The net present value associated with the purchase of two machines initially is $77,900 if demand is low and $137,100 if demand is high. The net present value for one machine and low demand is $98,000. If demand is high, there are three options. One option is to do nothing, which would have a net present value of $119,680. A second option is to subcontract; that would have a net present value of $115,650. The third option is to…arrow_forwardDemand has grown at Dairy May Farms, and it is considering expanding. One option is to expand by purchasing a very large farm that will be able to meet expected future demand. Another option is to expand the current facility by a small amount now and take a wait-and-see attitude, with the possibility of a larger expansion in two years.Management has estimated the following chances for demand: The likelihood of demand being high is 0.80. The likelihood of demand being low is 0.20. Profits for each alternative have been estimated as follows: Large expansion has an estimated profitability of either $51,600 or $23,600, depending on whether demand turns out to be high or low. Small expansion has a profitability of $13,800, assuming that demand is low. Small expansion with an occurrence of high demand would require considering whether to expand further. If the company expands at that point, the profitability is expected to be $41,900. If it does not expand further, the profitability is…arrow_forwardSuppose that an aircraft manufacturer desires to make a preliminary estimate of the cost of building a 600-MW fossil-fuel plant for the assembly of its new longdistance aircraft. It is known that a 200-MW plant cost $100 million 20 years ago when the approximate cost index was 400, and that cost index is now 1,200. The cost-capacity factor for a fossil-fuel power plant is 0.79. Estimate the cost using power sizing method.arrow_forward

Plan C has a flat rate of $80 with 200 minutes ofcalls allowed per month and a charge of $.40 per minute beyond that, day or evening.a.

The first alternative is expected to cost $1,000,000 and has an expected profit of $500,000 over the next three years. The second alternative has an expected cost of $800,000 and an expected profit of $450,000 over the next three years. Which alternative should we select, and what is the expected value of the expansion? Assume a 10 percent interest rate.arrow_forward
- Eastman Publishing Company is considering publishing an electronic textbook about spreadsheet applications for business. The fixed cost of manuscript preparation, textbook design, and web-site construction is estimated to be $170,000. Variable processing costs are estimated to be $5 per book. The publisher plans to sell single-user access to the book for $45. (a) Build a spreadsheet model in Excel to calculate the profit/loss for a given demand. What profit can be anticipated with a demand of 3,700 copies? For subtractive or negative numbers use a minus sign. $ (b) Use a data table to vary demand from 1,000 to 6,000 in increments of 200 to test the sensitivity of profit to demand. Breakeven occurs where profit goes from a negative to a positive value, that is, breakeven is where total revenue = total cost yielding a profit of zero. In which interval of demand does breakeven occur? (i) Breakeven appears in the interval of 3,800 to 4,000 copies. (ii) Breakeven appears in the interval of…arrow_forwardA firm is selling two products—chairs and bar stools—each at $50 per unit. Chairs have a variable cost of $25, and bar stools $20.

If the sales mix changes to 1:4 (one chair sold for every four bar stools sold), what is the break-even point in dollars of sales? In units of chairs and barstools?arrow_forwardA company has a factory that is designed so that it is most eficient (average unit cost is minimized) when producing 15,000 units of output each month. However, it has an absolute maximum output capability of 17,250 units per month, and can produce as little as 7,000 units per month without corporate headquarters shifting production to another plant. If the factory produces 10,925 units in October, what is the capacity utilization rate in October for this factory?arrow_forward
