Textbook Question
Chapter 11, Problem 21P
An aerodynamic three-wheeled automobile (the Dart) runs on compressed natural gas stored in two cylinders in the rear of the vehicle. The $13,000 Dart can cruise at speeds up to 80 miles per hour, and it can travel 100 miles per gallon of fuel. Another two-seater automobile costs $10,000 and averages 50 miles per gallon of compressed natural gas. If fuel costs $8.00 per gallon and MARR is 10% per year, over what range of annual miles driven is the Dart more economical? Assume a useful life of five years for both cars.

- ← 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%.
