Write an equation and solve. Round to hundredths as needed. Markup and Discount PRE-ALGEBRA LESSON 6-9 (For help, go to Lesson 6-7.) Write an equation and solve. Round to hundredths as needed. 1. What is 75% of $82? 2. What is 42% of $170? 3. What is 5.5% of $24? 4. What is 80% of $15.99? Check Skills You’ll Need 6-9

1. What is 75% of $82? 2. What is 42% of $170? Markup and Discount PRE-ALGEBRA LESSON 6-9 Solutions 1. What is 75% of $82? 2. What is 42% of $170? n = 0.75 • 82 n = 0.42 • 170 n = 61.5 n = 71.4 75% of $82 is $61.50. 42% of $170 is $71.40. 3. What is 5.5% of $24? 4. What is 80% of $15.99? n = 0.055 • 24 n = 0.80 • 15.99 n = 1.32 n = 12.79 5.5% of $24 is $1.32. 80% of $15.99 is $12.79. 6-9

_________ is the amount of increase in price. Markup and Discount PRE-ALGEBRA LESSON 6-9 Vocabulary _________ is the amount of increase in price. Percent of Increase is _______________________ _________________________________________ _____________ is the amount of price decrease. Percent of discount is ________________________ 6-9

markup = percent of markup • store’s cost Markup and Discount PRE-ALGEBRA LESSON 6-9 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 = percent of markup • store’s cost = 0.2 • 1.25 = 0.25 Simplify. The markup is $.25. Quick Check 6-9
