conversations.value: Dino works 20 hours at a rate of $10 an hour, which means that work pays him 20*10=200 dollars a month
  Dino works 30 hours at a rate of $20 an hour, which means that work pays him 30*20=600 dollars a month
  Dino works 5 hours at a rate of $40 an hour, which means that work pays him 5*40=200 dollars a month
  Altogether, this means Dino makes 200+200+600= 1000 dollars a month.
  You subtract Dino's expenses of 500 from this amount, meaning he has 1000-500=500 dollars at the end of the month
