a. What is Kiwidale's MARR that makes the two alternatives equivalect? Use a present worth comparison. Hint: Use i=0.15 and in 0.20 for the linear interpolation. The MARR that makes the two altematives equivalent is approvimately 18.5 percent. (Round to one decimal place as needed.) b. It tumed out that the service life of Smoothie was 14 years. Which altemative is better on the basis of the MARR computed in part (a)? Assume that each aiternative can be repeated indefinise Cick the icon so view the table of compound interest factors for discrate compounding periods when i 18.6%. The annual worth of the Smoothie ice-cream maker is \$ The annual worth of the Creamy ice-cream maker is $ The ice-cream maker is the beber altemative. (Round to the nearest cent as needed.)
