Answer: $6,287.95
Explanation: There are two pieces to consider when calculating the cost of a trade. First, you need to calculate the total cost of the stock. Pfizer is trading for $31.40, so the total amount for 200 shares is $6,280. The second piece is what the brokerage firm charges for the trade. In this case it is $7.95. The total for this trade is $6,280 + $7.95, which equals $6,287.95.
