What formula do I use to solve the below question?

FarCry Industries, a maker of telecommunications equipment, has 3 million shares of common stock outstanding, 1 million shares of preferred stock outstanding, and 10,000 bonds. Suppose the common shares sell for $24 per share, the preferred shares sell for $13.00 per share, and the bonds sell for 97 percent of par.
