Consider a stock currently priced at $$80.$ In the next period, the stock can either increase by $30$ percent

or decrease by $15$ percent. Assume a call option with an exercise price of $$80$ and a risk$-$free rate of $6$

percent. Suppose the call option is currently trading at $$12.$ If the option is mispriced, what amount

of riskless return can be earned using a riskless hedge?
