You own a firm, and you want to raise $35 million to fund an expansion. Currently, you own 100% of the firm's equity, and the firm has no debt. To raise the $35 million solely through equity, you will need to sell two-thirds of the firm. However, you would prefer to maintain at least a 50% equity stake in the firm to retain control.

you will need to sell ___% of the equity.(Round to one decimal place.)
