Mr. Digman is selling his famous Peanut Butter and Jelly sandwiches for $1.50 a piece and ham sandwiches for $2.00 a piece. During his rush, he didn't keep track of how much of each sandwich he made but knows that he made 32 sandwiches based on how much bread is gone. He also knows that he made $55.50 from the sandwich sales. How many of each sandwich did he sell?
