A rural utility company provides standby power to pumping stations using diesel-powered generators. An alternative has arisen whereby the utility could use a combination of wind and solar power to run its generators, but it will be a few years before the alternative energy systems are available. The utility estimates that the new systems will result in savings of $15,000 per year for 3 years, starting 2 years from now and $25,000 per year for 4 more years after that, i. e., through year 8. At an interest rate of 8% per year, determine the equivalent annual worth for years 1 through 8 of the projected savings. Solve using

One of the scarce resources that constrain our behavior is time. each of us has only 24 hours in a day, and we must allocate our time in a given day among competing alternatives. how do you go about allocating your time in a given day among competing alternatives? how do you go about weighing the alternatives? once you choose a most important use of time, why do you not spend all your time on that activity? a. as more and more time is spent on one activity, the opportunity cost of that activity in terms of other activities rises. b. as less and less time is spent on one activity, the opportunity cost of that activity in terms of other activities rises. c. as more and more time is spent on one activity, the opportunity cost of that activity in terms of other activities falls. d. b and c only.
