Several supervisors who have experience with similar projects have identified key attributes and their view of relative importance.

If there is a 20% chance that the PW will be the pessimistic one of $45,000 and 50% chance that it will be the most likely one of $72,000, the optimistic PW is closest to: (a) $89,520 (b) $118,380 (c) $126,670 (d) $138,540arrow_forward
- A manufacturing company has the choice of two suppliers to buy a piece of equipment from to use in its process. Characteristics of these two suppliers and associated costs are tabulated below. The equipment from supplier A costs more to buy and maintain, but it also has more revenue per unit sold. Selling enough units will at some point make it worth the higher cost. How many units per year must the company sell in order to justify using supplier A (i.e. what is the breakeven number of units to sell)? Use an interest rate of 12% per year. Supplier A Supplier B Initial cost $4,000 $3,000 Sale price (revenue per unit) $4 $3 Transportation costs (per unit) $0 $1.25 Annual maintenance cost $1,400 $1,100 Salvage value $800 $700 Useful life of the equipment (years) 5 4arrow_forwardYour Area Director wants to purchase new ergonomic office equipment for your staff. The total purchase price is quoted by Herman Miller to be $22,656. The main reason for the proposed purchase is the high rate of lost work days due to low back and wrist/hand issues. These are common problems associated with poor ergonomic position and repetition. You can sell the equipment in 8 years and have a salvage value of $4,619. It is estimated that the purchase of the new equipment will cut your lost work days by 61% and save you an estimated $11,812 per year in the costs associated with the lost work days. What is your EUAW for this proposed purchase at an interest rate of 6%?

The MTTR must be between 10 and 28 hr, and the MTBF must be at least 1200 hr. Consider the cost functions as: a. C(x) = 0.0002x2 ; C(y) = 12500/y b. C(x) = 2x; C(y) = 2000-y 2.arrow_forward
- Assume a pool of 115 people in an insurance pool (a group of people insured through community rating). It is estimated that a small number in the pool will have significant pre- existing conditions as indicated in the table. Based on the age of these 115 people, the insurance company estimates the following distribution of health care claims (which includes necessary profit and administrative costs of the insurance company). Number of Insured Antidipated Heath Costs/Year/Person $1,400 $1,500 $1,600 $1,700 $1,800 $1,900 $2,000 $2,100 $2,200 $2.300 $2,400 $2,500 $2,700 $2,000 $2,900 $3,000 $3,100 $3.200 $3.300 $4,000 57,00 $10,000 Everyone joins the poal ad pays the necessary premum in the first year.

City officials have questioned the number and profitability of the luxury corporate boxes planned for the upper deck of the stadium. Corporations and selected individuals may buy the boxes for $340,000 each. The fixed construction cost for the upper deck area is estimated to be $5,780,000, with a variable cost of $170,000 for each box constructed. (a) What is the break-even point for the number of luxury boxes in the new stadium? x = (b) Preliminary drawings for the stadium show that space is available for the construction of up to 52 luxury boxes. Promoters indicate that buyers are available and that all 52 could be sold if constructed. (ii) What profit is anticipated? (Enter a negative value if a predicted loss.) $arrow_forward3arrow_forward
