Find a couple of sales flyers that have arrived in the mail or that are available online. Take a few minutes to leaf through the flyers. Focus on how the consumer is encouraged to make purchases from the stores advertising in the flyers.
Are the flyers attractive and well laid out, and do the flyers highlight items of interest? Are there items on sale for less than regular price? Are percent discounts featured or are the dollar values of the discounts displayed? How can you tell, for instance, if $10.00 off is as good as a discount of 20%?
Percents
percent: out of a hundred
The symbol for percent is %.
Did You Know?
The percent symbol, %, is just a shorthand way for writing /100.
When you are working with percents, an important skill is being able to convert among percents, decimals, and fractions.
Self-Check
Work with a partner, if possible. Explore Conversions. Save this table of percents, fractions, and decimals in your course folder.
The first two rows have been completed for you. Do you see the pattern of how the representation of values changes between a percent, a fraction, and a decimal?
SC 1. to SC 3. Fill in the empty squares in the table using the patterns you discovered.
