8. (1.5 points) You own your own firm, and you want to raise $60 million to fund an expansion. Currently, you own 100% of the firms equity, and the firm has no debt. To raise the $60 million solely through equity, you will need to sell three-fifth of the firm. However, you would prefer to maintain at least a 50% equity stake in the firm to retain control. If you borrow $40 million, what fraction of the equity will you need to sell to raise the remaining $20 million? (Assume perfect capital markets.).
