Eaton Electronic Company's treasurer uses both the capital asset pricing model and the dividend valuation model to compute

the cost of common equity $($also referred to as the required rate of return for common equity$).$

Assume:

$R_f=3\%$

$K_m=8\%$

$=1\mathrm{.}2$

$D_1=$$$0\mathrm{.}35$

$P_0=$$$14$

$g=8\%$

a$.$ Compute $K_i($required rate of return on common equity based on the capital asset pricing model$).$

Note: Do not round intermediate calculations. Input your answer as a percent rounded to $2$ decimal places.

b$.$ Compute $K_e($required rate of return on common equity based on the dividend valuation model$).$

Note: Do not round intermediate calculations. Input your answer as a percent rounded to $2$ decimal places.
