An oil refinery finds that it is necessary to treat the waste liquids from a new process before discharging them into a stream. The treatment will cost $40,000 the first year, but
process improvements will allow the costs to decline by $4,000 each year. As an alternative, an outside company will process the wastes for the fixed price of $20,000/year
throughout the 8 year period, payable at the beginning of each year. Either way, there is no need to treat the wastes after 8 years. Use the annual worth method to determine
how the wastes should be processed. The company's MARR is 13%.

A road can be paved with either asphalt or concrete. Concrete costs $20,000/mile and lasts for 20 years. What is the maximum that should be spent on asphalt, which lasts only 10 years? The annual maintenance costs are $500/mile for both pavements. The cost of money = 8%.

Both machines make the firm’s production process more efficient which in turn increases incremental cash flows. The GSU-3300 produces incremental cash flows of $24,998.00 per year for 8 years and costs $99,590.00. The UGA-3000 produces incremental cash flows of $29,475.00 per year for 9 years and cost $126,038.00. The firm’s WACC is 8.32%. What is the equivalent annual annuity of the GSU-3300?

While work continues on these grand challenges, conservation of energy from non-renewable sources is vital. On a practical level, installing low thermal emissivity windows (low-e windows) on buildings can contribute to energy conservation. Installing low-e windows on a small office building is estimated to cost $10,500. The windows are expected to last 9 years and have no salvage value at that time. The energy savings from the windows are expected to be $2,525 in the 1st year. After the 1st year, the savings are expected to increase by $200 each year due to escalating fossil fuel costs. MARR is 12% per year and annual worth is the preferred measure of economic worth. Part a Are the low-e windows an economically attractive investment?
