I work with a register, and there has been times where I accidentally inputted more change than what the customer gave me. For example. Say the total came out to be $50.00 and the customer hands me $100.00 , but I accidentally inputted $1000.00 leaving the change to be $950.00 . How can I figure out the correct

I work with a register, and there has been times where I accidentally inputted more change than what the customer gave me. For example. Say the total came out to be $50.00 and the customer hands me $100.00 , but I accidentally inputted $1000.00 leaving the change to be $950.00 . How can I figure out the correct amount of change if I were to make another mistake such as this .

### Best Answer:

**paulina:** If you typed $1000 instead of $100, the difference is $900.

The displayed change is $950, so just subtract $900 from that to get the actual change.

Another example: total is 23$, customer hands you $50, you type $500 (diff: $450)

Change displayed is $477, actual change is $450 less, $27.

I'm wondering how useful this is though, because the simplest calculation is

customer's bill – total

So my advice for the cashier would be to ignore what the register says when they made a mistake and simply calculate the change manually (or using a calculator).

This makes me so sad 🙁

In middle school i learned how to do this. Not from class though. I learned this from no other than the lunch lady. (Not joking)

Everyday she would use it as an oppritunity to teach.

If the balance owed as 10.34 and i gave her a 20.

She would say "Figure out your change first , add from 34 up to 100 that's the change part."

For that example i'd give back 6 cents(40)+ (60 cents(100)… so 66 cents.

That leaves me with 11$ Now from 11$ to get to 20 i'd add 9 to the 20.

9.66 cents is the amount of change i got back.

I'm only entertaining this question because Lunch ladies don't get enough credit for the impact they have on children.

This kind of upsets me. It is basic math. I recall running a register in drive thru for years. I would never enter the amount they gave me. It is very easy for people who understand numbers well to figure Total $9.52, given $10.00 change .48

Total 21.42 Given 50.00 (Customer says wait I have 2 dollars) Given 52.00 change 30.58

You just need to use math skills. It isn't hard. You ask how do I calculate numbers when the calculating computer cant help me? Well, you calculate.

My recommendation is to not allow those kinds of mess-ups to go through. In the end your mistake will become a problem when it comes time to tally up the nights income, which in turn will make your tally short. The best thing to do, whether inconvenient or not is to void the transaction and redo the sale. Cash registers make it easy for you to not actually have to count. All the results are in front of you and all you have to do is give them the correct change. Unless your using an old register that does not do the math for you, voiding the transaction and redoing it is the only option.

Change is just counting, start with the smaller change to get to a 5 or ten, then get to an even dollar, then count dollars to the five or ten, then to what they gave you. It's how it used to be done, it's just counting,

Learn Math. Basic 3rd grade math will help you with most of that. (If this question is even real.)
