conversations.value: Can you break down the solution for me for this math problem: A class is 40% boys. The rest are girls. Every boy in class gets an 80% on the math test. Every girl gets a 90%. What is the class average on the test?
conversations.from: assistant
conversations.value: The class is 60% girls because 100 - 40 = 60
  The class average is 86% because .4(80) + .6(90)= 86
