You Answered Correct Answer MTU is considering acquiring a new industrial carpet cleaner machine. It has three options. Clean Smart: purchase cost of $348,775 and operating costs of $25,109 in year 1, $25,060 in year 2, and $26,571 in year 3 (paid at the end of each year). Shining Floor: purchase cost of $216,938 and operating costs of $39,437 in year 1, $37,021 in year 2, and $39,451 in year 3 (paid at the end of each year). Spring Breeze: purchase cost of $255,888 and operating costs of $21,535 in year 1, $22,004 in year 2, and $20,000 in year 3 (paid at the end of each year). Assume that MTU has a budget of $308,019 for this investment and all carpet cleaners have a service life of 3 years. Based on the defender-challenger approach and given that the MARR is 8%, reinvestment rate is 7%, and minimum external rate of return is 6%, compute the incremental Benefit-Cost ratio of choosing the best carpet cleaner (in economic terms) and then indicate your recommendation as follows: - answer "0" (without the commas) if your recommendation is the Clean Smart; - answer "1" (without the commas) if your recommendation is the Shining Floor; - write down as your answer the value the incremental B-C ratio if your recommendation is the Spring Breeze. Note: round your answer to two decimal places, and do not include spaces, currency signs, plus or minus signs, nor commas. 1 1.15 margin of error +/-0.05 You Answered Correct Answer MTU is considering acquiring a new industrial carpet cleaner machine.
