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.
Unlike profit, which gets measured in dollars and cents, profit margin gets measured as a percentage. To measure profit margin, use the companyâs net income divided by the total sales generated. For example, the furniture store had a net income of $100,000 and generated $500,000 in sales. To determine the store's profit margin, divide the net income ($100,000) by the total sales revenue ($500,000) and the store has a 20% profit marginâ$100,000/$500,000 = 0.20 or 20%. The profit margin also acts as a gauge of a companyâs control on operating costs.
