Parkway Subdivision
Dear Ms. Zubiri
Thank you very much for all you have taught me of Business Mathematics.
I feel that I have gained much that will be invaluable in the years to come. Above all, I deeply appreciate your patient endeavor to help me put into practice what you have so clearly explained. Without such practice, the course would not have been so profitable.
Among the treasures which I shall take back to Singapore will be the remembrance of your interesting yet informative lectures
Very truly yours,
Ricardo L. Quintero
