Lesson 1: Buying Furniture and Appliances Consumer Math p. 170-173

Exercise A Rosa purchases a couch at a “45% off” sale. If the sale price is \$494.99, what was the original price? 1. Subtract the discount from 100% (100%-45% = 55%) 2. Round the sale price to the nearest dollar to make the calculation easier (\$494.99 = \$495.00) 3. To find the original price, divide the rounded sale price by the percent paid (\$495.00 /.55 = \$900) The original price is \$900.00. Note that the original price may have actually been listed as \$899.99.

Example B Frank buys a lamp for \$49.99. The regular price is \$129.99. What discount does he receive? 1. Round the prices to the nearest dollar(\$49.99 = \$50.00; \$129.99 = \$130.00) 2. Subtract the sale price from the regular price to find the amount saved (\$130-\$50 = \$80) 3. Write the ratio (amount saved / regular price) (\$80 / \$130 =.615).615…round = 62%
