【正确答案】[写作范文]
Dear Mr.Goodson，
I was wondering if you would grant your permission over our application for a laptop computer．Due to the increased work in data process and data analysis，we have to recruit another staff to do the increased amount of work．But the thing is，we have no other computer available for the new staff．As you know，the outdated computers are all replaced last year due to the poor effeciency and the several new members employed this year have used the few left computers．So we decide to apply for one computer for the new staff．
We have conducted a marketing survey for the target computer and found that the HP，DELL and LENOVO computer all could meet our need．All of the three have excellent processing power and high speed．We could not make up our mind as to which one to choose until recently，I happened to read such an advertisement for a company which provides laptop computers．They would like to give us a cut in price if we could buy the DELL computer before 15th October．
The next Monday is thirteenth October，on which the new staff is to come to work with US and in order to buy the computer at a discount，we suggest the purchase be fullfilled by this Sunday
I am looking forward to your reply．Best wishes for you
