MassGlass Corporation is a firm with $60 million in equity and $35 million in debt. The debt has maturity of 5 years. If we view the equity of this firm as a call option, then we can evaluate this option as one whose exercise price is $ 35 million, whose time to expiration is 5 years, and whose underlying asset has a value of $ ??? million.

I thought the answer for ??? was 25 but that is not correct.
