Hyde Park Elementary has plans to build a new playground in 2017. They received a $120,000 government grant to be used for building the playground. They are hoping to break ground in May 2017 and complete the project by the start of school in September. Before they can start the project, however, they must dismantle the existing playground that has become unsafe based on current safety standards. They are also planning to complete soil testing once the existing playground is dismantled as a number of residential properties in the community have tested positive for soil contamination. Due to recent news articles, parents are very concerned about the potential for soil contamination and are demanding a full test to ensure their kids are not playing on a contaminated playground.

Sonya Muhammed, the school principal, has compiled the following estimates related to the new playground:

The costs for installation, resurfacing, landscaping, and soil removal are the costs quoted by professional contractors. Sonya was approached by the president of the student council, Josh Schwinn, who has volunteered the council’s time for installing and landscaping the new playground. This will save the school approximately $25,000 in costs and Sonya has decided to accept this offer as two of the council members who will be helping are journeymen carpenters.

The school has two options in terms of dealing with the contaminated soil. The first option is to not partake in the soil testing and to simply resurface the play area with a poured-rubber matting that can cover the entire play surface. This will cost, as Sonya indicated in her estimates above, approximately $55,000 – a large chunk of the playground budget. The other option is to perform the soil testing. A municipal worker has estimated that there is a 40% chance that the soil is contaminated. If this is the case, the school will either need to resurface the area for $55,000 or it can have the contaminated soil removed and replaced for a hefty cost of $73,000 plus the cost of gravel. However, there is a 60% chance that the soil will not be contaminated. Sonya is wondering what they should do and has asked for your help.

REQUIRED

Prepare an analysis of the potential project costs for the following scenarios. Note: There is no need for gravel in the resurfacing scenario.

1. Resurface ground without doing soil testing .
   
2. Complete the soil testing. In this case there are two outcomes:

1. remove/replace the soil if contaminated.
2. resurface if contaminated.
   

Use the probabilities provided by the municipal worker to determine a weighted cost for each of these outcomes.

3. What option would you recommend for the school? Why? Are there other non-financial considerations that you need to include in your decision?

Parker & Stone, Inc., is looking at setting up a new manufacturing plant in South Park to produce garden tools. The company bought some land 3 years ago for $4798465 in anticipation of using it as a warehouse and distribution site, but the company has since decided to rent these facilities from a competitor instead. If the land were sold today, the company would net $3848715. An engineer was hired to study the land at a cost of $823164, and her conclusion was that the land can support the new manufacturing facility. The company wants to build its new manufacturing plant on this land; the plant will cost $4984348 million to build, and the site requires $1185814 worth of grading before it is suitable for construction. What is the proper cash flow amount to use as the initial investment in fixed assets when evaluating this project?

Parker & Stone, Inc., is looking at setting up a new manufacturing plant in South Park to produce garden tools. The company bought some land six years ago for $3.6 million in anticipation of using it as a warehouse and distribution site, but the company has since decided to rent these facilities from a competitor instead. If the land were sold today, the company would net $4.1 million. The company wants to build its new manufacturing plant on this land; the plant will cost $18.1 million to build, and the site requires $950,000 worth of grading before it is suitable for construction. What is the proper cash flow amount to use as the initial investment in fixed assets when evaluating this project?

Elaine was enjoying a pleasant day on the ski slopes at Winter Park. When she got on the lift to the top of Parsenn Bowl (12,000 ft), the weather was fine—windy, but sunny. During the 5- or 10-minute ride, the weather changed suddenly; it became a white-out, with icy surface snow, blowing snow, a very strong wind, and extremely low visibility. Many people fell as they got off the lift, including Elaine. However, she got up and joined her family members as they stood, wondering just how they were going to get down the mountain. Meanwhile, the lift closed due to the terrible conditions (50-mile-an-hour wind and a temperature of −20° F). As she adjusted her stance, Elaine somehow twisted and fell again, which resulted in external rotation of her right knee. There was no pain at the time and she thought she could get up and prepare to get down the mountain, but her knee was too unstable. While she sat on the icy surface, her husband notified the lift operator to call the Ski Patrol. In about 20 minutes they arrived and put her on a sled, which they skied down the slope; when they reached the Ski Patrol headquarters, they transferred the sled to a snowmobile and promptly got her down the mountain and into the emergency room.

What would happen to her body if the homeostatic mechanism failed?

What areas of the body would be the most vulnerable to frostbite?

What are the signs and symptoms of frostbite?

Give an example of a negative feedback mechanism that is describing her condition right now. Label all of the components and put what is occurring in her body at this time.

•South Park Energy is considering replacing the company's Methane Plant with a Nuclear Plant.

•The Methane Plant was built two years ago at a cost of $120M with an expected useful life of 5 years. This plant is being depreciated to zero using 5-year straight-line depreciation. The Methane Plant can be sold today for $70M. If this plant had been kept, it would have had no salvage value at the end of its expected useful life three years from today.

•The Nuclear Plant would cost $500M to build today. Since the Nuclear plant will just be a working prototype, its expected useful life is only 3 years and it falls in the 3-year MACRS depreciation class (yr 1: 33%, yr 2: 45%, yr 3: 15%, yr 4: 7%). The Nuclear Plant is expected to have a salvage value of $40M at the end of the plant's 3-year life. The Nuclear Plant is expected to reduce operating expenses by $150M each year during the plant's 3-year expected life and increase revenues by $40 million each year. The company's marginal tax rate is 40%, and this project has a weighted average cost of capital of 13%.

(Q1) What is the total cash flows during year 3 for this replacement analysis?

(Q2) What is the initial cash flow for this replacement analysis?

An amusement park studied methods for decreasing the waiting time (minutes) for rides by loading and unloading riders more efficiently. Two alternative loading/unloading methods have been proposed. To account for potential differences due to the type of ride and the possible interaction between the method of loading and unloading and the type of ride, a factorial experiment was designed.
