Percent literally means “out of 100,” or “compared to 100.” Percentages are written with the %
symbol. If we have half of something it is the same as 50% because 50 is half of 100.
The practice problems in this section use the concept “out of 100” to help you visualize what is
happening when we add or subtract a percentage from another amount. We will go into this in
more detail in the next few mini-lessons.

Practice Problems
1. What does a percent mean?
2. If an item purchased at a store costs $1 and has a sales tax rate of 6%, what will be the
total amount paid for the item?
3. If a tire store is having a sale for 10% off any tire, and you purchase a tire that normally
costs $100, what is the sale price of the tire after the 10% is taken off?
4. If you earn 20% commission for any sale you make, and you sell $100 worth of product,
how much will you earn for that sale?
