Then, take the difference, divide it by the initial price, and then multiply by 100.

To find what percent of number y is number x, you should divide number x by number y. Then multiply your result by 100 and this will give you the percentage. Your formula should look like x/y * 100.
To find what number of x is a total of some percentage, you should divide the known percentage by 100 and multiply your result by number x. Your formula should look like y%/100 * x.

You can work out the percentage of something by using the fraction method or the decimal method. To use the decimal method, turn the percentage into a decimal, by dividing the percentage by 100: 50 per cent becomes 0.5; 60 per cent 0.6; 20 per cent 0.2.
