conversations.value: Sam is twice as old as Sue. Kendra is 3 times as old as Sam. If Kendra is currently 18, what will be their total age in 3 years?
  Work out the solution step by step.
conversations.from: assistant
conversations.value: Sam is currently 18 / 3 = 6 years old.
  Sue is currently 6 / 2 = 3 years old.
  In three years, Sue will be 3 + 3 = 6.
  In three years, Same will be 6 + 3 = 9.
  In three years, Kendra will be 18 + 3 = 21.
  Their total age in three years is 6 + 9 + 21 = 36.
