Answer:
13.7%
Explanation:
The weight to be placed on preferred while computing the company's weighted average cost of capital (WACC) is the market value of the preferred stock divided by the market value of the company as a whole.
market of preferred stock=5,000*$26=$130,000
Market value of the company=market value of common stock+market value of preferred stock+market value of bond
common stock market value=12,000*$39=$468,000
market value of bond=$400,000*87%=$348,000
Weight of preferred stock=$130,000
/($130,000
+$468,000+$348,000)=0.137420719
=13.7%
