Suppose you believe that florio company's stock price is going to decline from its current level of $82.50 sometime during the next 5 months. for $5.10 you could buy a 5-month put option giving you the right to sell 1 share at a price of $85 per share. if you bought this option for $5.10 and florio's stock price actually dropped to $60, what would your pre-tax net profit be? a) $5.10 b) $19.90 c) $20.90 d) $22.50 e) $27.60

B. $19.90

Step-by-step explanation:

The put option will be exercised only if the final price is below the strike price. If the final price exceeds the strike price, there will simply be a loss equal to the cost of the option.

total $17.40

< xcy ≅ < xby

step-by-step explanation:

in δcax and δbax,

so, δcax ≅ δbax (side-angle-side or sas)

since δcax ≅ δbax, we can conclude < acx ≅ < abx

in δacy and δaby,

so, δacy ≅ δaby (side-angle-side or sas)

since δacy ≅ δaby, we can conclude < acy ≅ < aby

now,

< acy ≅ < aby

=> < acx + < xcy ≅ < abx + < xby

=> < acx + < xcy ≅ < acx + < xby   (since < acx ≅ < abx already proved above)

subtracting < acx from both sides, we get

< acx + < xcy -< acx ≅ < acx + < xby -< acx

cancelling out < acx and -< acx from both sides, we get

< xcy ≅ < xby (proved)
