BREAK-EVEN ANALYSIS
Consider a hybrid vehicle with a price of $30,000. This vehicle will average
30 miles per gallon of gasoline. A comparably equipped gasoline-only vehicle will
cost $28,000 and will average 25 miles per gallon of gasoline. Assuming an interest
rate of 3% per year and a study period of five years, find the breakeven cost of
gasoline ($/gal) if the vehicle will be driven 18,000 miles each year.
J. Doe must choose between two different models. The analysis period considered is 6
years. Model 1 has a life of four years with a first cost of $13,500 and maintenance
costs of $1,250 per year in years 2, 3, and 4 (no maintenance costs in year 1). The
salvage value for this model at the end of its life is $4,271 (For year 2 the salvage value
is $7,594).
Model 2 has a life of three years with a first cost of $15,000 and maintenance costs of
$700 per year. Its salvage value at the end of its life is $9,300 (year 3).
Which of the two models should be chosen by J. Doe if considering a MARR of 12%.

An L-shaped bracket is used for relatively small fireplace openings and a Ushaped bracket is used for all others. The company includes both types of brackets in the box with their product and the purchaser discards the one not needed. The cost of these two brackets with screws and other parts is $3.50. If the frame of the fireplace screen is redesigned, a single universal bracket can be used that will cost $1.20 to make. However, initial costs of retooling ($6000) and inventory writedowns ($8000) will be incurred immediately. If the company sells 1200 fireplace units per year, should the company keep the old brackets or go with the new ones, assuming the company uses an interest rate of 15% per year and it wants to recover its investment in 5 years.
