The mean cost of domestic airfares in the United States rose to an all-time high of $385 per ticket. Airfares were based on the total ticket value, which consisted of the price charged by the airlines plus any additional taxes and fees. Assume domestic airfares are normally distributed with a standard deviation of $120. Use Table 1 in Appendix B. a. What is the probability that a domestic airfare is $560 or more (to 4 decimals)? b. What is the probability that a domestic airfare is $260 or less (to 4 decimals)? c. What if the probability that a domestic airfare is between $310 and $510 (to 4 decimals)? d. What is the cost for the 2% highest domestic airfares? (rounded to nearest dollar) $ or more/less.

A cable runs along the wall from C to P at a cost of ​$3 per​ meter, and straight from P to M at a cost of ​$5 per meter. If M is 16 meters from the nearest point A on the wall where P lies, and A is 59 meters from C, find the distance from C to P such that the cost of installing the cable is minimized and find the cost

2. If produced by Method A, a product’s initial capital cost will be $100,000, its operating cost will be $20,000 per year, and its salvage value after 3 years will be $20,000. With Method B there is a first cost of $150,000, an operating cost of $10,000 per year, and a $50,0000 salvage value after its 3-year life. Based on a present worth analysis at a 15% interest rate, which method should be used?

Zankel Incorp is considering replacing its old machine with a new machine. The cost of a new machine is RM 300,000 with a useful life of 4 years. The machine has an estimated salvage value of RM 45,000. The cost of installing this new machine will be RM 20,000. In the initial period, RM 125,000 in net working capital is required and to be recovered at the ending life of the machine. The company was using the present machine for 4 years and it has a remaining useful life of 2 years. The machine was bought at RM 200,000 and has a salvage value of RM 20,000. Currently, the machine can be sold at RM 90,000 and normally the company adopts straight- line method as a depreciation strategy. The new machine is expected to result in changes as follows:

• Increase in annual sales by RM 80,000.

• Reduction in annual defect cost by RM 6,000.

• Increase in annual operating cost by RM20,000

The average cost of tuition and room and board for a small private liberal arts college is reported to be $8,500 per term, but a financial administrator believes that the average cost is higher. A study conducted using 350 small liberal arts colleges showed that the average cost per term is $8,745. The population standard deviation is $1,200. Let α = 0.05.

Man-U-Facturing Inc. will buy a machine that has a cost of $850,000 and is expected to be useful for 10 years. At the end of the 10th year, the firm intends to sell the machine for an estimated price of $52,036. In addition, the yearly benefits are expected to be $201,952 while the annual maintenance costs are predicted to be $51,300. The company uses a 9% interest rate for this project and it is currently being taxed at a flat tax rate of 21%. Assume Man-U-Facturing Inc. using SOYD depreciation. What is the after-tax IRR?

using SOYD depreciation. What is the after-tax benefit-cost ratio?

using SOYD depreciation. What is the after-tax net present value (NPV)?

For many years businesses have struggled with the rising cost of health care. But recently, the increases have slowed due to less inflation in health care prices and employees paying for a larger portion of health care benefits. A recent Mercer survey showed that 52% of U.S. employers were likely to require higher employee contributions for health care coverage. Suppose the survey was based on a sample of 700 companies. Compute the margin of error and a 95% confidence interval for the proportion of companies likely to require higher employee contributions for health care coverage.

If required, round your answer to four decimal places. Round intermediate calculations to four decimal places.
