Q: I heard that the old $20’s would be unusable. Is this true? Are the old $20 bills still going to be in circulation, or will we have to change any old bills for new ones? If so, do we have a time limit?
— Dawn S., Denver
A: Not true. The old $20s are good forever. Over time, the Treasury will pull the old ones out of circulation, but you don’t neet to trade them before any set deadline. The average “lifespan” of a $20 bill is about two years, but you’ll no doubt still see them in circulation for years.
Q: What is the average inflation rate for the last five years, per year? Please respond quickly as I need this answer before class in the morning. — Angela R., Woodstock, Va.
A: Sorry, Angela: we have two rules here at the Answer Desk. We don’t making recommendations on specific investments. And we don’t do other people’s homework. That would be cheating, wouldn’t it?
