(Ignore income taxes in this problem.) The management of Stanforth Corporation is investigating automating a process. Old equipment, with a current salvage value of $15,000, would be replaced by a new machine. The new machine would be purchased for $408,000 and would have a 6 year useful life and no salvage value. By automating the process, the company would save $141,000 per year in cash operating costs. The simple rate of return on the investment is closest to:

Suppose the government decides to issue a new savings bond that is guaranteed to double in value if you hold it for 20 years. assume you purchase a bond that costs $25. a. what is the exact rate of return you would earn if you held the bond for 20 years until it doubled in value? (do not round intermediate calculations and enter your answer as a percent rounded to 2 decimal places, e. g., 32.16.) b. if you purchased the bond for $25 in 2017 at the then current interest rate of .27 percent year, how much would the bond be worth in 2027? (do not round intermediate calculations and round your answer to 2 decimal places, e. g., 32.16.) c. in 2027, instead of cashing in the bond for its then current value, you decide to hold the bond until it doubles in face value in 2037. what annual rate of return will you earn over the last 10 years?
