RED 2012 BOOK

4.3 Activity

You can find 10% and multiply by the correct amount.  Ex: 40% off of \$50.00  10% is \$5.00.  \$5.00 X 4 (for 40%) = \$20.00  So 40% off of \$50.00 is \$20.00  How much would you have to pay?

4.3 Activity When you save 40%, you pay 60%  40% of \$50.00 is \$20.00  So 60% of \$50.00 is \$30.00.

4.3 Activity

Finding the original price is the same as finding the whole. \$22.40 is the part. What percent does \$22.40 represent of the original price? \$22.40 is 70% of what number? Why is 70% used instead of 30%? 30% off the original price is the same as paying 70% of the original price.

4.3 Activity A store purchases an item for x dollars. The store needs to sell this item for more than x dollars (markup) to cover operating costs and to make a profit. A store purchases an item for \$2 and sells it for \$4. This represents a 100% markup (\$2 + 100% of \$2).

4.3 Activity Reasoning: If a \$10 item sells for \$25, the \$10 item was marked up 150% and the selling price is 250% of \$10. (100% of \$10) + (150% of \$10) = (250% of \$10) = \$25

4.3 Activity

4.3 Lesson Yesterday you explored discounts and markups using a percent bar model. Today you will use the percent proportion to find discounts and markups of items.

A store buys an MP3 player for \$100 and marks it up 50%. The store has a 50% off sale. You purchase the MP3 player. What do you pay? Did the store lose money?

4.3 Lesson The amount of discount is a part of the whole original price. The percent equation or percent proportion is used to find the amount of the discount. A 25% discount is the same as paying 75% of the original price. A 30% discount is the same as paying ____% of the original price. A 60% discount is the same as paying ____% of the original price.
