See if you are On The MONEY today

Once in a while The Think Tank will make sure your "on your game".

Thus we present small brain teaser this day for you to test tha 'ol NOGGIN.

Joey decided to "cash in" on his sisters piggy bank. He gets a total of $8.20. Somehow he manages to take out the exaxct same number of quarters, nickels, dimes and pennies.

Question: How many of each did he take?

What Say You??

He found 20 of each coin. Just add up the total of those 4 coins and divide $8.20 by that number! 25=10=5=1+41 8.20/.41=20 Thanks for making me use my ol' noggin!

ok, I came up w/ 20 each as well, but I didn't arrive at my answer the same way. I just thought about it for a few seconds and 20 each sounded like a good starting point, so I did the math and added it all up to $8.20. I've always been good w/ figures, especially making change (helps to have been a bank teller and cashier!). helping my 7th-grade son w/ his math homework is another matter though: I can come up w/ the answer he needs, but I don't know how to apply the formulas the school wants him to use!

I am good in math also and just figured that 20 sounded like a good starting point what with the cents being 20. I did the math and it all added up. Thanks for the fun!
