Assume the dividend payout ratio each year is 100%. a. Calculate the yearbyyear book and economic profitability for investment in polyzone production. Assume straightline depreciation over 10 years and a cost of capital of 8%. (Negative answers should be indicated by a minus sign. Leave no cells blank be certain to enter "0" wherever required. Do not round intermediate calculations. Enter your income answers in millions rounded to 2 decimal places and enter the rate of return as a percent rounded to 2 decimal places.)

b1. What is the economic rate of return? (Do not round intermediate calculations. Enter your answer as a percent rounded to 2 decimal places.)

b2. Now compute the steadystate book rate of return (ROI) for a mature company producing polyzone. Assume no growth and competitive spreads. (Negative answers should be indicated by a minus sign. Do not round intermediate calculations. Enter your answer as a percent rounded to 2 decimal places.)
