請注意,我們在這個工具的工廠價基礎上加上百分之5的操作費用,因爲這個操作會讓我們產生很多額外的費用,例如報關費,文件費,運輸等.

解答：

Please be noted that based on the factory price of this tool, an additional operation fee of 5% will be added thereto because such operation will incur a large amount of additional fees, such as customs clearance fee, document related fee, delivery fee, etc.
