Consider a project to supply Detroit with 25,000 tons of machine screws annually for automobile production. You will need an initial $2,200,000 investment in threading equipment to get the project started; the project will last for 5 years. The accounting department estimates that annual fixed costs will be $700,000 and that variable costs should be $380 per ton; accounting will depreciate the initial fixed asset investment straight-line to zero over the 5-year project life. It also estimates a salvage value of $300,000 after dismantling costs. The marketing department estimates that the automakers will let the contract at a selling price of $480 per ton. The engineering department estimates you will need an initial net working capital investment of $220,000. You require a return of 12 percent and face a marginal tax rate of 22 percent on this project.

  

a-1

What is the estimated OCF for this project? (Do not round intermediate calculations and round your answer to the nearest whole number, e.g., 32.)

a-2

What is the estimated NPV for this project? (Do not round intermediate calculations and enter your answer in dollars, not millions of dollars, rounded to 2 decimal places, e.g., 1,234,567.89.)

b.

Suppose you believe that the accounting department’s initial cost and salvage value projections are accurate only to within ±15 percent; the marketing department’s price estimate is accurate only to within ±10 percent; and the engineering department’s net working capital estimate is accurate only to within ±5 percent. What is the worst-case NPV for this project? The best-case NPV? (A negative answer should be indicated by a minus sign. Do not round intermediate calculations and enter your answer in dollars, not millions of dollars, rounded to 2 decimal places, e.g., 1,234,567.89.)

An example of an RCRA Corrective Action site is Boeing Plant 2 in Seattle, Washington. There was contamination of PCBs, PAHs, phthalates, semi-volatile organic compounds in the soil on-site and in surrounding waterways (including groundwater). Boeing still occupies the area and it is handling the cleanup, which is still ongoing. Part of their process has been implementing pilot projects that have reduced groundwater contamination by 98% (US EPA 2013). Since Boeing is still active on-site, RCRA Corrective Action is appropriate.

An example of a Superfund site is Quendall Terminals in the state of Washington. Located on Lake Washington, on 29 acres, this Superfund site was previously acreosote manufacturing and oil storage facility for many decades. Creosote, coal tar, and other hazardous chemicals have accumulated in groundwater, lake sediment and on land (US EPA 2019). While the lake is not used as a drinking water source, there are swimming beaches within a half-mile from the site (US EPA 2005). In 1999, the state’s Department of Ecology began contamination cleanup. Then in 2005, at the state’s request, EPA took over. The EPA requested the site’s responsible parties conduct a remedial investigation and feasibility study. The remedial study was completed in 2012 and the feasibility study completed in 2017 by the responsible parties. Public comments were received from September to October 2019 and the EPA’s final cleanup plan is scheduled (US EPA 2019). As the location is no longer in use and currently vacant, the CERCLA program is appropriate for this site. Additionally, there are plans to rezone and repurpose the location for residential use.

Write program that draws out a path based on the user input. The starting coordinates for the path is the middle of the DrawingPanel. Ask the user to enter an x and a y coordinate for a DrawingPanel. Your program will draw a line from the last coordinates to the current coordinates the user enters. If the user enters an x value or y value out of bounds of the DrawingPanel, then end the program.

An equilibrium mixture contains 0.20 moles of hydrogen gas, 0.80 moles of carbon dioxide, 0.10 moles of carbon monoxide, and 0.40 moles of water vapor in a 1.00-liter container. How many moles of carbon dioxide would have to be added at constant temperature and volume to increase the amount of carbon monoxide to 0.20 moles? The equation for the reaction is:

CO(g)+H2O(g) <=> CO2 (g)+H2 (g)
