Activity: Copy or print out (right-click / print) the table below. Find the sale price for each listed amount, and then fill in the Sale Price column. One method commonly used by many people is to compute the discount first, and then subtract to find the sale price. There is another way! Look over the completed Sale Price column. Try to devise another way to find the sale price by simply multiplying the original price by a percent that gives the sale price. (Hint: If an item is on sale for 10% off, then the sale price would be 90% of the original price.) Complete the second One-Step Percent Multiplier column. Refer to the completed table to answer the next three questions. |
