Using incremental rate of return, determine which of the following options is the most cost effective provided a minimum annual rate of return (MARR) of 18%, a useful life of 10 years, and the following data: Option 1: Initial Cost: $50,000 Annual Cost: $7,000/ year with an annual increase of $500 each year Repair Cost at year 8: $20,000 Salvage Value: $35,000 Option 2: Initial Cost: $35,000 Annual Cost: $9,000/ year with an annual increase of $1,000 each year Repair Cost at year 6: $12,000 Salvage Value: $15,000
