  15. Do you ever wonder what deal is better? Example: 40% off a $24.50 sweater Or The same sweater 20% off but it’s $32.25

  16. Knowing how to Use percents can help you!

  17. Using Percents in the Real World Percentages are commonly used in everyday life. When you pay for something, whether it is a product or a service, percents are almost always involved. Most often percents are used to calculate discounts, tips, and sales tax.

  18. Discounts Pay Less!

  19. American Eagle is having a 10% off sale. If Chandler wants to buy a sweater whose regular price is $30.50, about how much will she pay for the sweater after the discount? Step 1: Find 10% of 30.50 30.50(.10) = 3.50 Discount = $3.05 Step 2: subtract discount from original price. 30.50 – 3.05 = 27.45

  20. Sales Tax Pay More!

  21. Ellyis buying a dog bed for $40.00. The sales tax rate is 7%. About how much will the total cost of the dog bed be? Step 1: Find 7% of 40.00 40(.07)=2.80 Step 2: Add to total bill to find the amount he paid! 40 + 2.80 = $42.80

  22. Tips Pay More!

  23. Joseph’s dinner bill from Longhorns is $17.85. He wants to leave a tip that is 15% of the bill. About how much should his tip be? How much will he have to pay total? Step 1: Find 15% of 17.85 17.85(.15) = 2.68 Step 2: Add to total bill to find the amount he paid 2.68 + 17.85 = $20.83

  24. Let’s Try Together!

  25. Problem #1 About how much do you save if a book whose regular price is $25.00 and is on sale for 10% off?

  26. Problem #2 Julie gets a 15% discount on all of the items in the clothing store where she works. If she buys a shirt that regularly costs $44.99, how much money will she save with her employee discount?

  27. Problem #3 A bead store has a sign that reads “20% off the regular price.” If Janice wants to buy beads that regularly cost $6.00,how much will she pay for them after the store’s discount?

  28. Problem #4 At Paint City, a gallon of paint with a regular price of $17.99 is now 15% off. At Giant Hardware, the same paint usually costs $21.99, but is now 20% off. Which store is offering the better deal?
