Answer:
Follows are the solution to this question:
Explanation:
[tex]\text{Equity expense = free risk rate+beta} \times \text{market risk premium}[/tex]
[tex]=3 \% + 1.2 \times 5 \% \\\\= 0.03 + 1.2 \times 0.05 \\\\= 0.03 +0.06 \\\\= 0.09\\\\=9 \%[/tex]
[tex]\text{Preferred inventory cost} = \frac{\text{annual dividend}}{( price - floation \ rate)}[/tex]
[tex]= \frac{(100 \times 5.46 \%)}{(100-100 \times 5 \%)}\\\\=5.75 \%[/tex]
[tex]\text{Excel feature = RATE(nper, PMT, PV, FV)}[/tex]
[tex]=(RATE( \frac{20 \times 2,1000 \times 12 \%}{2,-1100,1000})) \times 2 \\\\=10.77 \%[/tex]
[tex]\text{Debt expense after tax}= 10.77 \% \times (1-40 \%)[/tex]
WACC from Preston = Capital weight [tex]\times[/tex] Capital equity costs+cost of common stock [tex]\times[/tex] cost of common shares [tex]\times[/tex] debt cost [tex]\times[/tex] (1-tax rate)
[tex]=60 \% \times 9 \%+20 \% \times 5.75 \%+20 \% \times 6.46 \% \\\\=7.84 \%[/tex]
