For normal % calculations, it works as follows:

100 x 5 % . . . the display should read 5

100 x 5 % + . . . the display should read 105 which is 5 added to 100

100 x 5 % - . . . the display should read 95 which is 5 subtracted from 100

The SET/% key is indeed dual function although SET isn't initiated until the button is pressed AND held down for a few seconds. When that is occurring, you display should be blank for those few seconds after which SET will be indicated on the display indicating it is ready for input.

otherwise, . . .

Make sure you are not in the SET mode. The display should be clear with nothing but 0 showing. You might also want to press AC before beginning calculations.

HOW DO I SET THE TAX RATE?

Posted on Jan 07, 2008

Helpful thank u

It sounds like the Percent key has a dual function. Thee should be a way to toggle the feature by either holding a function or 2nd key then pressing the percent key. Good luck. John

Do it the old fashioned way. 6%= .06

20% of 600 =600 x .20.

Just remember percentage is hundredths.

20% of 600 =600 x .20.

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.

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.

- Create a blank workbook or worksheet.
- Select the example in the Help topic.
**Note**Do not select the row or column headers.

Selecting an example from Help - Press CTRL+C.
- In the worksheet, select cell A1, and press CTRL+V.
- 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.

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?

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.

Hi. Try this steps on using your math calculator for the percentage function.

Hope This Helps

Step 1. Note that not all calculators behave the same way as far as the percentage key is concerned. Thus, test the examples in this article on your calculator. If your calculator does not have the percent key or does not behave in the way described here, don't despair - you can still use it to calculate percentages, it's just that you will have to press a few more buttons.

Step 2. Let's calculate a tip on your restaurant bill. Suppose your bill happens to be $64.35 and you would like to leave 15% tip.

Type the following into your calculator: 64.35 * 15 %

Answer: 9.6525 or $9.65 after rounding.

Most simple calculators will give an answer right here without having to press the = sign. If yours does not, press = and see if you get the right answer.

Alternatively, you can calculate this percentage by typing in

64.35 * 15 / 100 or 64.35 * 0.15

Thus, you may have observed that all that the percent key did here was division by a hundred.

Step 3. Let's calculate a grade percentage - say you got 34 out of a maximum of 40 points.

To figure out your grade percentage type in: 34 / 40 %

Answer: 85

Alternatively, without the percent key: 34 / 40 * 100

Step 4. Let's calculate a sale price on those shoes that originally cost $139, but are now discounted by 35%.

On your calculator type in: 139 - 35 % =

Answer: 90.35 or $90.35

This calculation is amazingly easy with the percent key! Alternatively, you would first have to calculate what the 35% of the $139 is and then subtract it from 139:

139 * 35 / 100 = 48.65

139 - 48.65 = 90.35

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.

Mar 05, 2010 | Casio Office Equipment & Supplies

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.

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

There is no other button to hold down to get the % button to work. It does have a dual function, it says RATE SET above the % sign.

Not sure how to get the % button to actually work, very frustrating!!

I can't seem to calculate simple percentages. I don't want to set a permanent tax rate... just want to calculate varying percentages. Anyone know how to do this?

change tax rate

I have lost my instructions on how to change my tax rate on my Casio MS-8TV, can you help?
