The Mu Alpha Theta Math Honors Society sells hot chocolate and coffee at the high school football games. At the last game, they had sales of $200. Students in the club need to keep track of how many of each type of drink was sold so that they can make predictions for future sales. Monica knows that they used 275 cups that night. If the hot chocolate sells for 75 cents, and coffee sells for 50 cents, how much of each type of drink were sold?
