You form a long straddle by buying a call with a premium of C = $6, and buying a put with a premium of P = $6. Both options have an exercise price of X = $27, both mature in 1 months, and both have the same underlying asset. Find the profit of this straddle when the price of the underlying asset is S = $49. Do NOT use the $ symbol in your answer; just write a numerical value. Of course, include the negative sign if the answer is negative; but do not include the positive sign if the answer is positive.
