conversations.value: Calvin signed up for a gym training service to lose some pounds. If he weighed 250 pounds to start with and lost 8 pounds every month during the training sessions, what's his weight after one year?
  How to solve this?

conversations.value: Since Calvin loses 10 pounds every month, his total weight loss after one year is 12*8 = 96 pounds.
  Calvin weighs 250-96 = 154 pounds after a year of hitting the gym.
