Dr. Fraser will cover Applications of Percents with examples of real life situations. You will learn about percentage of increase which is illustrated with sales tax, as well as percentage of decrease which can be understood as a discount.
A percent of
change is an increase or decrease expressed as a percent. If the
new value is greater than the original one, it is a percent of
increase; otherwise, it is a percent of decrease.
Sales tax is a
familiar example of a percent of increase.
Discount is an
example of a percent of decrease.
When solving these
kinds of problems, always write the percent as either a fraction
with a denominator of 100 or a decimal equivalent to the percent.
