svp [43]

Answer:

WACC = 11.45 %

Explanation:

Weighted average cost of capital is the average cost of all of the long-term types of finance used by a company weighted according to the that amount of finance used in relation to the total pool of fund

WACC = (Wd×Kd) + (We×Ke) + (Wp × Kp)

After-tax cost of debt = Before tax cost of debt× (1-tax rate)

Kd-After-tax cost of debt = 11.1%(1-0.4) =6.66%

Ke-Cost of equity = 14.7%

Kp= Cost of preferred stock = 12.2%

Wd-Weight of debt =100/270=0.370

We-Weight of equity = 140/270=0.518

Wp= weight of preferred stock = 30/270=0.111

WACC = (0.518× 14.7%) + (0.370 × 6.7%) + (0.111×12.2) =  11.447%

WACC = 11.45 %

Olegator [25]

This calculation is shown below:

Opportunity cost of time = $13

cost of admission into carnival = $9

Total cost of skipping practice = opportunity cost of time + cost of admission into carnival

= 13 + 9 = $22
