conversations.value: Please show me the solution for: Texas Integrated School has 15 classes and has 20 students per class.  They added five more classes, how many students will they have now?

conversations.value: The school has 15 x 20 = 300 students right now.
  They have an additional 5 x 20 = 100 students after adding 5 more classes.
  Therefore, Texas Integrated School will have a total of 300+100= 400 students.
