Compute K_e and K_n under the following circumstances: a. D_1 = exist8.00, P_0 = exist82, g = 7%, F = exist6.00. (Do not round intermediate calculations. Round your answers to 2 decimal places.) b. D_1 = exist.50, P_0 = exist46, g = 3%, F = exist4.50. (Do not round intermediate calculations. Round your answers to 2 decimal places.) c. E_1 (earnings at the end of period one) = exist13, payout ratio equals 40 percent, P_0 = exist46, g = 3.5%, F = exist2.10. (Do not round intermediate calculations. Round your answers to 2 decimal places.) d. d_0 (dividend at the beginning of the first period) = exist6, growth rate for dividends and earnings (g) = 4%, P_0 = exist72, F = exist3. (Do not round intermediate calculations. Round your answers to 2 decimal places.)
