<prompt> Human: Id like to try to help my parents out with getting their financial house in order since theyve been struggling with both debt and liquidity for some years. This question is about where they should put their priority on a couple of credit card debts.They have about 6,500 of debt on two credit cards: 1,800 at 10 4,700 at 4Theyre currently employing avalanche to pay off the highest interest cards first. Recently theyve paid off a couple other higher interest cards, so theyre making good progress, if slowly.Should they continue to use avalanche and pay off the higher interest card even though its the lower balance, or pay off the lower interest card first even though its higher balance?My concern here is their liquidity, which has major shifts from year to year because they own their own business. Ive discussed with them areas they should cut out high cable bill primarily but theres other things they can do but I dont know how much Ill be able to make them budge on this in the short term. Also, Im concerned that a couple bad months at the business could set them back even further on paying this off.Thanks for any advice!  <response>: Pay off the higher rate debt first. Balance is irrelevant. This is a question I wish every middle school kid knew how to answer.
