Sometimes a radio program is added to the carrier in such a way that the program signal causes fluctuations in the carrier's frequency. This is called frequency modulation (FM). Another way of sending a radio signal is to make the peaks of the carrier wave bigger or smaller.
Calculating the percentage profit made. It is also possible to work out the percentage profit that is made on a deal. This is done using the profit and the price that something cost originally, before it was sold on (the Cost Price). Percentage Profit = (profit/cost price) x 100%. The next example shows how this is done. Example.
The formula for the net profit ratio is to divide net profit by net sales, and then multiply by 100. The formula is: (Net profit / Net sales) x 100. The measure could be modified for use by a nonprofit entity, if the change in net assets were to be used in the formula instead of net profit.
