Hubbard's Pet Foods is financed $60\%$ by common stock and $40\%$ by bonds. The expected return on the common stock is $13\mathrm{.}5\%,$ and

the rate of interest on the bonds is $7\mathrm{.}5\%.$ Assume that the bonds are default$-$free and that there are no taxes. Now assume that

Hubbard's issues more debt and uses the proceeds to retire equity. The new financing mix is $30\%$ equity and $70\%$ debt. Assume the

debt is still default free.
