A stock priced at $$50$ has two possible outcomes, either increases to $$60$ or decreases to $$42.$ If the stock goes up$,$ the payoff of the stock's call option $=$ $$5.$ But, if the stock price declines to $$42,$ the calls will expire worthless. Given these two possible outcomes, what is the Hedge Ratio of the Call option? Round your answer to two decimals.

The listed correct answer was $0\mathrm{.}28.$ I could not find a way to get this.
