【简答题】
There is a letter about reference sales. Dear Sir: How would you like to increase the efficiency of your office staff by 10% this summer? Tests in over 80 business offices using Glux air conditioners have proved that staff efficiency in these offices increased by 10% after the Glux was installed. As the increased staff efficiency means greater profits, you will therefore get back your cost within a limited period of time.

In addition, improvements in the new model will also make your operating costs low. Won't you call and ask us to send you our technical personnel to identify your specific needs and do the installation? Each day's delay costs you money. Yours Faithfully, Tony Smith Chief seller What is the purpose of the letter? To sale ______.
