Persuasion

I tried to persuade my teacher to pass me in his class. He said we could buy him a Starbucks gift card and the more money we put on it the higher he would raise our grade. I only bought him a ten dollar girt card because I couldn't afford much more than that. Since I had an F in his class he only raised the percentage the next day when I gave it to him. It went from 29% to one percent away from a D. I asked him if I dressed for the remainder of the year if he would raise it a little more. Unfortunately, he disagreed. I was disappointed but I asked him if I brought him Mcdonald's breakfast if he would pass me. He agreed and I passed with a low D in the end.
