This is probably one of the most irrelevant and unrealistic posts I will ever write, but I figured it’d be fun to know and share with others. The secret to always having enough change for something isn’t in the amount of coins you have; it’s in the type of coins you have. Obviously no one is going to refill their wallet with this exact change combination every time they go shopping, which is why I said it’s unrealistic, but let’s proceed anyways, shall we?
The magic formula for always having exact change is the following:
The concept is simple enough; for each coin, that is the exact number of coins you need before it turns into the next type of tender. For example, if you had any more than 1 nickel, you would just use a dime. Therefore you will never need more than 1 nickel in your wallet, ever, so long as you carry dimes as well. I’m not exactly a rocket scientist for ‘coming up with this’, it’s just an obvious technique I picked up as a cashier. So if you ever find your wallet over-filled with coins and you don’t know which to keep and which to take to the bank, just keep enough to fulfill the magic combination!
And thus concludes the most random blog post I have ever written.
