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.
Input a formula in the final column to calculate the profit margin on the sale. The formula should divide the profit by the amount of the sale, or =(C2/A2)*100 to produce a percentage. In the example, the formula would calculate (17/25)*100 to produce 68 percent profit margin result.
