Explanation:

capital structure:

cost of equity 11%

cost of preferred stock 5%

cost of debt 7%

tax rate 35%

WACC = (0.7 x 11%) + (0.05 x 5%) + [0.25 x 7% x (1 - 35%)] = 7.7% + 0.25% + 1.1375% = 9.0875% = 9.09%

after tax cost of debt = 7% x (1 - 35%) = 4.55%

enjoy the dunce cap fool

hi : ) i found this so i hope this !

"we first find value of tax in dollars.

the difference between the two prices   is: 23. 54 - 22 = 1.54

therefore the sales tax in dollars is 1.54

the tax % will be   (amount of tax / original cost price ) × 100

(1.54 / 22) × 100  → (0.07) × 100 =   7

so the tax rate is 7%

we can double check the answer.

7 % of 22   → (7/100) × 22 → 0.07 × 22 = 1.54

22 + 1.54 = 23.54"
