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? Let's think first. Chain of thought:
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.
Therefore, the answer is 20.
