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.
3. Type the different percentages in column A. 4. Select the range A12:D17. We are going to calculate the total profit for the different combinations of 'unit profit (highest price)' and '% sold for the highest price'. 5. On the Data tab, click What-If Analysis and select Data Table from the list. 5. Click in the 'Column input cell' box (the percentages are in a column) and select cell C4. We select cell C4 because the percentages refer to cell C4 (% sold for the highest price).
