Can someone please answer this.

Given investors' required rate of return (r_d) on a bond is 10%: Compute the cost of capital (k_d) when the firm is subject to 40% tax rate (T) and flotation cost (F) is 5%. Use k_d = [r_d x (1 - T)/ (1 - F)]. Capital Cost (k_j) Weight (w_j) Bond 6% .3 Preferred 10% .1 Common 20% .6 Given the capital structure, compute, the WACC (k_w) correctly, [k_w = summation (k_i x w_i)], if each capital is given equal weights, i.e., 1/3 each. Given the cash flow of a project below: Year 0 Years 1 - 10 ($5,019) $(1,000) Compute NPV = [PV of benefit - PV of cost] when the cost of capital (k_w) is 12%. find IRR using the equation [PV of cost = PMT Times PVAF_r, n]. Would you accept the project? Why or why not? The following is the cash flow from investment in a permanent working capital. Year 0 Years 1 - infinity ($6,000) $(480) Compute: NPV when cost of capital (r) is 7% (PV = PMT/r), IRR (r) = PMT/PV), benefit (annual benefit - annual cost)
