You would normally use the decimal point to separate the major currency unit (for example Pound or Euro) from the minor currency unit (Pennies or Cents).
It shows that the thing is bigger then what it is and they know that the decimal is rounded and they also know that it will have a decimal in it
There's no such thing.
IT DOESN'T COST A THING IT DOESN'T COST A THING
To calculate a percentage off a cost, first determine the percentage you want to take off. Convert that percentage into a decimal by dividing it by 100. Multiply the original cost by this decimal to find the discount amount, then subtract that discount from the original cost. For example, if an item costs $50 and you want to take 20% off, the discount would be $50 × 0.20 = $10, so the final price would be $50 - $10 = $40.
That would be almost impossible to determine.
After rounding to 2 decimal places, 6.09 would be the cost.
It would cost whatever a wrecked donor car would cost you to buy. Otherwise buying new parts would be cost prohibitive. The smart thing to do would be to sell the car you now have and then buy a Kia Spectra 5 speed.
The conversion cost is the amount of money it takes to change a resource into a product. Going from something raw to a finished product would almost always have a cost, that would be the conversion cost. The cost at which it takes to convert from one thing to another.
If 100 envelopes cost 79 cents, the cost per envelope is 0.79 cents divided by 100, which equals 0.0079 cents per envelope. For 250 envelopes, the cost would be 250 multiplied by 0.0079 cents, totaling approximately 1.975 cents. Therefore, 250 envelopes would cost about 1.98 cents when rounded to two decimal places.

cost * (1 - discount % as a decimal)
82.47*(1-.25) = 61.8525$ total or 82.47*(.25) = 20.6175$ off To find the percent off of an item, take the original cost and multiply it by the decimal your percentage comes out to be. For 25%, you would multiply your cost by .25 to get the amount you save. To find the new cost, subtract what you save from the original cost. You new cost would be 61.86 asuming they round up.
