Answer:
WACC= 6.24%≈ 6.2%
Explanation:
Weighted average cost of capital(WACC)= {(S/T)*r1}+ {(D/T)*r2)*(1-R)}
Let us define the terms
Stockholder Equity (S)= $6,000
Total value of business= S+D= 4,000+6,000= 10,000
Cost of equity(r1)= 8%
Debt(D)= $4,000
Cost of debt)r2)= 6%
Tax rate(R)= 40%
Therefore
WACC= {(6,000/10,000)*0.08}+ {(4,000/10,000)*0.06* (1-0.40)}
WACC= 0.048 + (0.024*0.6)= 0.048+0.0144
WACC= 0.0624
WACC= 6.24%
