Which is More?
Date: 05/21/2002 at 20:02:55 From: bridget Subject: money You are offered a choice of nickels stacked on top of each other to equal your height, or quarters placed side by side to equal your height. Which would you choose and why? I tried several different ways to get this answer but I'm not good with numbers and I can't figure out the anwser. Please help me. Thank you, Bridget

Now the problem is easier, isn't it? You just have to stand a quarter on its edge, stack some nickels up until they reach the top, and see whether the nickels add up to more than 25 cents. If they add up to more than 25 cents, you would choose the nickels. Otherwise, you'd choose the quarter. Does that make sense? Now, suppose you're TWO quarters high, instead of just one. Or three quarters high. Or five, or six, or seven, or any number of quarters high. Would there be any reason to make a different choice? - Doctor Ian, The Math Forum http://mathforum.org/dr.math/
