(Do not round intermediate calculations, Round your answer to 2 decimal places.) Rate of return b. What will be the divisor for the price-weighted index in year 2? (Do not round intermediate calculations. Round your answer to 2 decimal places.) Divisor c. Calculate the rate of return of the price-weighted index for the second period (=1 to 2) Rate of return %
