Whenever you need to find the percentage OF a number (often money), you just convert that percentage to a decimal (just move the decimal to the left twice so 40% becomes 0.40, 10.5% becomes 0.105, 2% becomes 0.02, etc) and MULTIPLY that decimal by the amount/number you need to find the percentage of.
For example, find the 20% commission of a $10,000 car sale Calculation: 0.20x$10000 = $2000 Answer: the commission would be $2000
