Explanation

The firm's Weighted Average Cost of Capital (WACC) is a weighted average of the component cost of capital. In this case 10%(borrowing rate) x (1-.4)Tax savings

= 6% is the component cost of debt. $10 (preferred dividend) / 97.5(Par minus floatation cost) = 10.25% is the component cost of preferred stock. Thus the WACC

= .4(6%) + .5(12%) + .1(10.25%) = 9.42%
