1. To Start – 10 Points!!! Find the percent of increase from 4 to 7.5. Amount of increase = 7.5 – 4 = 3.5 Original amount = 4 The percent of increase from 4 to 7.5 is 87.5% Find the percent of increase from 11 to 18.5. Amount of increase = 18.5 – 11 = 7.5 Original amount = 11 The percent of increase from 11 to 18.5 is 68.2%

2. CHAPTER 6: RATIOS, PROPORTIONS, AND PERCENTS Section 6-9: Markup & Discount

3. Markup!!! To make a profit, stores charge more for merchandise than they pay for it. The amount of increase is called the markup.

4. Markup!!! A music store’s percent markup is 67%. A CD costs the store $10.15. Find the markup. Markup =.67(10.15) Markup = $6.80
