conversations.value: I need a clearer understanding of how to solve: Monica is a teacher. She has 6 classes per day. The first class has 20 students. The second and third classes have 25 students. Her fourth class has half as many as her first class. Her fifth and sixth classes have 28 students. How many students does Monica see each day?

conversations.value: Monica has 20+25+25+28+28=126 in 5 of her classes.
  In the fourth class, she has 20/2=10 students.
  In total, she has 126+10=136 students per day.
