I will be visiting my son over the weekend for the Arlington Million Horse Race in Chicago, IL, so I will be out of touch until Tuesday.
NO GOOGLING OR SEARCHING THE INTERNET FOR THE ANSWER. GOOD LUCK
RIDDLE:A certain investment doubles Joe's money every five years. If Joe leaves all the money invested, in 40 years he'll have 384,000. How long will it take to have $340,000 if he starts with twice as much money? How much money did he start with?

Starting with twice as much
Starting with twice as much would be just like doubling the money in the first five years, so he'd wind up with the same amount, $384,000, in five fewer years. So in 35 years he'd have $340,000, and in fact $44,000 more than that. I don't think we have enough information to determine when, if ever, he would have exactly $340,000  it would depend on how the investment could be cashed in.0
