conversations.value: I would love to understand how to solve this problem: Jim decides to go to college to earn some more money.  It takes him 4 years to finish and he gets $50,000 in loans per year.  If he had a 25k a year job before college and his college degree tripled his income, how long would it take to earn the money equivalent to the loans and the money lost from not working while in school.
  Can you explain?

conversations.value: His salary increased to 25000*3=$75,000 per year
  So he earns an extra 75,000-25,000=$50,000 a year
  His loan cost 50,000*4=$200,000
  He lost out on 25,000*4=$100,000 from not working
  So he needs to make 200,000+100,000=$300,000
  That means it will take 300,000/50,000=6 years
