conversations.value: I'm stuck on this math problem: $240 was divided between Kelvin and Samuel. Samuel received 3/4 of the money. From his share, Samuel then spent 1/5 of the original $240 on drinks. How much does Samuel have left?
  Can you help?

conversations.value: Samuel received 3/4 of $240, which is $240*(3/4) = $180
  He spent 1/5 of $240, which is $240*(1/5) = $48
  He spent this amount from his own share, so he has $180-$48 = $132 left.
