i need help with this

Reference the options chain for Caterpillar, Inc. (ticker: CAT) shown below. You bought one contract of the $115 strike call. At contract expiration, the shares of CAT traded at $140. What is your profit (or loss) on the strategy? State your answer in total dollar terms (i.e., total out-of-pocket cost not factoring transaction costs), not contract-level terms. Your answer should be a dollar amount with two decimal places of accuracy. Losses should be entered as a negative number. (Note on viewing table below: You may have to use a horizontal scrollbar to see all of the columns in the table below.)
