I already have the answers but I dont understand it$.$ Please explain it to me$.$ This is a call option question

Swenson Software has a pure discount bond with a face value of $$100.$

The bond is due in a year. At that time, the assets in the firm will be

worth either $$55$ or $$160,$ depending on the sales success of Swenson's

latest product. The assets of the firm are currently worth $$110.$

If the risk$-$free rate is $10$ percent, what is the value of the equity in

Swenson?

The value of the bond?

The interest rate on the bond?
