2 Markup and Discount PRE-ALGEBRA LESSON What is 75% of $82?2.What is 42% of $170? n = n = n = 61.5n = % of $82 is $ % of $170 is $ What is 5.5% of $24?4.What is 80% of $15.99? n = n = n = 1.32n = % of $24 is $ % of $15.99 is $ Solutions 6-9

3 Markup and Discount PRE-ALGEBRA LESSON Vocabulary _________ is the amount of increase in price. Percent of Increase is _______________________ _________________________________________ _____________ is the amount of price decrease. Percent of discount is ________________________ _________________________________________

4 A grocery store has a 20% markup on a can of soup. The can of soup costs the store $1.25. Find the markup. Markup and Discount PRE-ALGEBRA LESSON 6-9 markup = percent of markup store’s cost = = 0.25 Simplify. The markup is $.25. Quick Check 6-9

5 A bookstore pays $4.60 for a novel. The percent of markup is 45%. Find the novel’s selling price. Markup and Discount PRE-ALGEBRA LESSON = 2.07Multiply to find the markup = 6.53 Store’s cost + markup = selling price. The selling price is $6.67. Quick Check 6-9

6 A camera that regularly sells for $210 is on sale for 30% off. Find the discount. Markup and Discount PRE-ALGEBRA LESSON 6-9 discount = percent of discount regular price = = 63 The discount is $63. Quick Check 6-9

7 Markup and Discount PRE-ALGEBRA LESSON 6-9 Solve. 1.The school store has a 65% markup on each stapler. Each stapler costs the store $2.10. Find the markup. 2.A clothes store pays $40 for a skirt. The percent of markup is 25%. Find the skirt’s selling price. 3.A pair of shoes that regularly sells for $94.99 is on sale for 30% off. What is the sale price? $1.37 $66.49 $50 6-9
