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.
Target profit simply can be calculated by the following formula: Let's say you want to reach the target profit of $1000, but you don't know what sales should be. So, your target profit = volume needed = TFC target prof/ SPU-VCU where; SPU=Selling price per unit and VCU= Variable cost per unit.
