Math test in class!

Peace upon you all and today I went to school. Today my whole class did a math test today, and I got all of it correct! Also, here's a challenge: Joanne played tennis once per month. Helen played three times per month. Together, they played half what the average tennis plays. How many times does the average tennis player play each year? 10,9,8,7,6,5,4,3,2,1... Times up! The answer is 96! Peace be upon you and I'll see you later! Bye!
