Littrell's Nursery needs a new irrigation system. System one will cost $145,000, have annual maintenance costs of $10,000, and need an overhaul at the end of year six costing $30,000. System two will have first year maintenance costs of $5,000 with increases of $500 each year thereafter. System two would not require an overhaul. Both systems will have no salvage value after 12 years. If Littrell's cost of capital is 4%, using annual worth analysis determine the maximum Littrell's should be willing to pay for system two.

A used machine costs $22681 to purchase . It has an annual maintenance cost of $ 10000 , a salvage of $ 5000, and a 13 year life. If the interest rate is 3% per year , compounded annually, what is the present worth cost of the machine?
Build modelA new engineer is evaluating whether to usea higher-voltage transmission line. It will cost $245,000 more initially, but it will reduce transmission losses. The optimistic, most likely, and pessimistic projections for annual savings are $21,000, $14,000, and $9,000 respectively. The interest rate is 7%, and the transmission line has a life of 30 years. (a) What is the present worth for estimated value of each scenario? (b ) What is the expected (mean) Present Worth?
