I need to reset the TAX percentage on my calculator

The LS-100TS has tax keys. I suspect (for I cannot have access to a manual, just the online brochure by Canon) that you have to switch left to right or up-down one of the tax keys then you enter the tax percentage. and toggle back into position.

Just follow these steps:

1) Enter the percentage of your Tax Rate (in your case 10)

2) Hold down the RATE key, SET key, and TAX+.

3) Then release the RATE key.

Your Tax Rate should now be set back to 10%.

Percentages are calculated by using the following equation:
amount/total = percentage
Where percentage is in decimal format.
What do you want to do?

Calculate the amount if you know the total and percentage For example, if you purchase a computer for $800 and there is an 8.9% sales tax, how much do you have to pay for the sales tax? In this example, you want to find 8.9% of 800.
Example The example may be easier to understand if you copy it to a blank worksheet.

1. Create a blank workbook or worksheet.
2. Select the example in the Help topic. Note Do not select the row or column headers.
   Selecting an example from Help
3. Press CTRL+C.
4. In the worksheet, select cell A1, and press CTRL+V.
5. To switch between viewing the results and viewing the formulas that return the results, press CTRL+` (grave accent), or on the Formulas tab, in the Formula Auditing group, click the Show Formulas button.

1 2 A B Purchase price Sales tax (in decimal form) 800 0.089 Formula Description (Result) =A2*B2 Multiplies 800 by 0.089 to find the amount of sales tax to pay ($71.20) Note To convert a number in percentage format to a decimal, divide it by 100. For example, the sales tax in this example (8.9) divided by 100 is .089.
Calculate the percentage if you know the total and amount For example, if you score 42 points correctly out of 50, what is the percentage of correct answers?

Simple way Amount/Total*100

1. To change the tax rate, first press AC.
2. Then press SET % for 2 seconds.
3. Next, press TAX+, then enter the new or current tax rate.
4. Enter the rate for a single digit tax rate such as 5% as 5, a single number; if you have a fractional percentage rate, such as 5.75%, enter it just that way: the 5, then a decimal and followed by 7& 5.
5. Then press SET % and you're done!

Press the red [C-CE] button twice, then the yellow [+TAX] button.
Then type in the Tax percentage. Press [+TAX] again and then the [C-CE] twice again.
This works for the EL-331A Calculator.

FINALLY figured out how to change the tax rate! Press AC. Press and hold the Rate Set (%) button UNTIL THE CURRENT TAX RATE IS DISPLAYED. Enter the new rate you want (such as 7.5). Press the Rate Set (%) button again.

The Tax- function allows you to take the total cost (sub-total + tax) and it will subtract the tax and leave you with the sub-total (before tax).

Example:

If the item you have is $5 and the tax is set to 5%... when you use the Tax+ key it'll give you 5.25.

Conversely, when you enter 5.25 and press the Tax- key and it will give you the base price of $5.

So the Tax- key removes the tax from the total amount.
It doesn't remove the percentage OF the total amount.

Press
On/AC
Hold the Set% per 3 secons,
Press the green button TAX+
Enter the new tax rate # (9.25)
Enter SET %

Hi nastyguy3000;

To calculate a percentage in excel you simply take
amount/total = percentage in your cell

Example A B Purchase price Sales tax (in decimal form) 800 0.089 Formula Description (Result) =A2*B2 Multiplies 800 by 0.089 to find the amount of sales tax to pay ($71.20)

Have Fun
