Example 1

If an item is discounted 20%, the sale price is what percent of the original price?

If the original price of the item is $400, how much is the dollar amount of the discount?

How much is the sale price? What are some ways that we can solve this problem?

Exercise 1

Solving Sales Price Problems

You are given the sale price and the percent that was saved and you need to come up with the original price. You should be creating models in order to prove that your answer is correct.

The following items were bought on sale. Complete the missing information in the table.

Hint: Fill in the percentages for Percent Saved or Percent Paid depending on what values are missing. We know that percent saved plus percent paid has to add up to 100%.
