conversations.value: Find the answer to the math problem: If Jenna has twice as much money in her bank account as Phil does, and Phil has one-third the amount of money that Bob has in his account, and Bob has $60 in his account, how much less money does Jenna have in her account than Bob?

conversations.value: If Phil has one-third of the amount that Bob does, that means he has $60/3= $20 in his account.
  Since Jenna has twice as much money as Phil, that means she has $20*2= 40 in her account.
  Since Bob has $60 in his account, that means he has $60-$40=$20 more than Jenna.
