Friday = payday for many of us, so it's a good time to offer a Brain Game all about cold, hard cash. Good luck!

Your pocket is stuffed with U.S. currency, but no coins and no $100 (or higher) bills. Given this information, what is the largest amount of money your pocket could hold without being able to give exact change for a $100 bill, a $50 bill, a $20 bill, a $10 bill, or a $5 bill?

Here is the SOLUTION.

SOLUTION:

I'll give both correct answers:

If you include $2 bills (which are still being printed on occasion, and are still legal tender), you could have as much as $143: one $50 bill, four $20 bills, one $5 bill, and four $2 bills.

If you didn't include $2 bills (and it's fine if you didn't) the maximum amount is $139: one $50 bill, four $20 bills, one $5 bill, and four $1 bills.
