Three European call options with the same expiry date on the same stock, have strike prices of $22, $23, and $24, respectively. The prices of the call options are $2.60, $2.10, and $1.90, respectively. One call option gives the holder the right to buy one share.

Present your strategy with a profit diagram and a payoff table. Identify two breakeven stock prices, the minimum and maximum profits of the strategy at the expiration of the options.
