Capital Source           Market Value        Weight           Cost Total     Weight  

Debt                            $8,400,000            27.71%             4.389 %      1.22%

Common stock           $24,190,000           71.17%              12.2%         8.68%

Preferred stock           $1,400,000              4.12%               3.5%         0.14%

Total                          $ 33,990,000          100.00%                            10.04%

Calculation of Market Value and Cost of Debt

Market Value = 8,000×($1,000×105%) = $8,400,000

Cost of Debt = interest × (1 - tax rate)

                      = 5.7% × ( 1-0.23)

                      =  4.389 %

Calculation of Market Value and Cost of Common stock

Market Value = 410,000× $59 = $24,190,000

Cost of Common stock = Risk free Rate + Beta × Market Premium

                                       = 4.5% + 1.10× 7%

                                       = 12.2%

Calculation of Market Value and Cost of Common stock

Market Value = 17,500× $80 = $1,400,000

Cost of Preferred stock = 3.5%
