Module 5: Proportions
and Percents
BY: JULIA MAIORINO, ALEXIS KERR, AND SARAH MORAN
Vocabulary Section 1
Percent Increase- describes how much a quantity increases in comparison to
the original amount.
Percent Decrease- describes how much a quantity decreases in comparision
to the original amount
Vocabulary Section 3
Simple Interest- a fixed percent of the principal
Principal- original amount of money deposited or borrowed
Formulas for Section 1
Percent of Change = amount of change
original amount
Amount of Change = greater value – lesser value
New Amount= original amount + amount of change
Formulas for Section 2
Retail price= original cost + markup
Sale price = original price - markdown
Formulas for Section 3
Simple Interest = principal x rate x time
Essential Questions
Section 1: What process do you use to find the percent change of a
quantity?
Given an original amount and a percent increase or decrease, you can use
the percent change to find the new amount.
Section 2: How can you determine the sale price if you are given the regular
price and percent of markdown?
You can turn the percent into a decimal and multiply the decimal by the
regular price. Then you subtract that answer from the regular price.
Section 3: How can you determine the total cost of an item including tax if
you know the price of the item and the tax rate?
You can turn the tax rate to a decimal then multiply it to the cost then add
what you got to the original price.
