### What does the MU/MD key on the Casio HR-100TM do?

Here's how to use the MU/MD key. Say you want your item that COSTS you \$120 to be priced such that you end up with a 40% margin. MU'MD calculates the final price to achieve the margin.

Enter: 120 X
Enter: 40 MU'MD
Result: 200.00

Proof: 200 - 120 = 80 / 200 = 40%

Essentially the same as using the COST/ SELL/ MAR keys.

The Casio HR-100Tm manual is pretty pathetic. Expected a better one on their website, but alas.

### I am trying to figure out how to use the Cost, Sell, and margin buttons on this calculator...any insight?

I haven't used a calculator with these functions, so let's do a test.

I'm guessing is it for doing basic accounting. The equation is Sales - Costs = Gross Profit and maybe Gross Profit / Sales = Gross Margin.

If we enter 100 in sell, 40 in cost, does the margin come out to be 60 or 0.6? If it comes out to 60, the margin is the Gross Profit. If it comes out to 0.6, then the margin is Gross Margin.

Good luck,

Paul

### I lost the manual for my sx-4000. How do I release the margins.

1. Press "return" key to left margin.
2. Press "margin release" key once.
3. Backspace to where you want the left margin
4. Press "Margin left" key.
For right margin, space bar to where it is, press margin release, space bar to where you want it, press "margin right" key.

### I must not understand what a margin is so could someone explain, the instructions give this example: If I purchase something for \$2000 and want to make a 20% profit I would need to sell it for \$2500 (2000...

Hi,
I think you should refer to you definitions. The 20% is called the markup. The profit margin is calculated with respect to the revenue. So you should divide the 400\$ by 2400\$ to get a net profit margin of 400/2400 =0.1667 or 16.67% (And we are not taking into account the taxes).

Margin = Markup /(price + Markup)
Markup = Margin* (Price +Markup)
Markup = Margin*Markup + Margin* Price
Markup*(1-Margin) =Margin*Price
Markup = Margin*Price/( 1-Margin)
For Price =2000, Margin =0.2 (that is 20%)
Markup = 0.2*2000(1-0.8) =0.2*2000/0.8
Markup = 2000*(0.2/0.8)= 2000*0.25 = 500

Thus to have a (net) profit margin of 20%, an item costing 2000\$ must be marked up by 500\$.

Try not to reason with numbers. Write the defining relation and use algebra to isolate for the variable you seek.

Hope it helps.

### How do I use the Cost/Sell/Margin function on my Canon P100-DH 2 desktop printing calculator? Please for the love of god help me.

Cost/Sell / Margin can be very confusing it uses the following Account formulas (For Cost = Selling price - ( Selling price / Markup) For Sell = Selling Price =Cost / (1-Margin%))

It is not a pure percentage. Please respond back if you have any other questions.

### I need to reset the left margin.

Use the code key..hold down while you press the left margin set key...if you have to go beyond the left margin press the mar rel key and backspace to the spot you want the margin to be. Then proceed using the code key and left margin set . On some typewriters turning them off resets all th margins..some it does not

### MARGINS

Move carrier to left margin press margin release, top left hand side of keyboard, back space to desired position and press L Margin key.  Margins will reset to default if batteries are dead.   Right margin simply space to whever you want the margin and press R Margin.

### Margin clearing and resetting

You cannot "clear" the margins. You have a left margin and right margin. They MUST be set somewhere even if they are set at the extreme left and right of the carriage. This part is IMPORTANT!!! Some functions (like right margin or margin release) may be written in a different color or shade. If they are, you must hold down the CODE or FUNCTION key while touching that function. In any case, the CODE key or similar will be the same color as the function you are trying to access. Get the printer where you want the margin to be. If you want the left margin set to the left of the current margin you will have use the MARGIN RELEASE key first. This may be labeled MREL or MAR REL or something similar. Backspace to where you want the margin to be then press the LMAR or LEFT MARGIN key. That will set the left margin at that point. Repeat the process for the right margin. Hope that helps Ed
