conversations.value: Find a solution for this math problem: Susan earns $5 every 10 minutes for an online task she does. If she works between 8 a.m. and 11 a.m. and pauses in between for half an hour, how much money does she earn for the online task?

conversations.value: Because she rests for half an hour, the time she works is 11 - 8 - 0.5 = 2.5 hours.
  So she works 2.5 * 60 = 150 minutes
  She earns $5 per 10 minutes, so for the online task she earns in total 150 * 5/10=$75.
