This and other similar strategies managers use is known as “playing the percentages.”
As mentioned, percentages are very important in business. An example of a very important business percentage is the gross profit percentage. This number is a key indicator of the current health of a business. Gross profit percentage is total revenue minus total costs divided by total revenue. This number is very useful because “comparing the company’s GPP at regular time intervals can determine how well the company is performing over time” (ehow, 2010).
Percentages interest me because they can be used in virtually every facet of life. While my feelings toward much of advanced math are often negative, concepts as simple and useful as percentages make me appreciate basic math concepts because I realize how important they are
