A professor was giving a big test one day to his students. He handed out all of the tests and went back to his desk to wait.
Once the test was over the students all handed the tests back in. The professor noticed that one of the students had attached a $100 bill to his test with a note saying "A dollar per point."
The next class the professor handed the tests back out. This student got back his test and $64 change.
一天，教授正在给学生们监考。他发下试卷，然后回到讲台前等待。
考试结束了，学生们纷纷交回试卷。教授发现一张试卷上别着一张百元钞票，还有一张纸条写着："一分一块钱。"
第二堂课，教授把试卷都发回学生们手中。其中一个学生不但得到了试卷还得到64块钱的找零。
