conversations.value: I'm completely lost with this math problem: Last year there were 50 students enrolled in a calligraphy class. This year, there was a 20% increase in enrollment. How many students are enrolled this year in the calligraphy class?
  Can you give me a hand?

conversations.value: There was an increase of 50 x 20/100 = 10 students in enrollment.
  So, there is a total of 50 + 10 = 60 students who were enrolled this year.
