1. Solving problems involving discounts at sales and sales tax. Number Sense 1.4 Calculate given percentages of quantities and solve problems involving discounts at sales, interest earned, and tips. Objective: Students will find the discount and sale price of an item and find the tax and total price of an item after taxes.

2. How to find the sales tax! • First find out what tax rate you will be paying. • In Michgan, the tax rate is 6%! • Convert your percentage to a decimal by moving your decimal two spaces to the left. Ex. 6% =0.06 (Don’t forget to add a zero) • Multiply the decimal form of the tax rate by the price of the item you are purchasing. Ex. 0.06 x \$ cost of the item

3. How to find the sales tax! • So if an item costs \$5.00 • Sales tax is6% • Convert 6% to 0.06 • So.06 x \$5 = \$0.30 • The sales tax is \$0.30 • But the total price of the item is \$5.00 + \$0.30 =\$5.30

4. How to find the Discount & Discounted Price • Find out the % of the discount. Convert the % to a decimal. • Multiply the decimal by the original price. • Take the answer in step 2 and subtract it from the original price. Example • Discount 20% = .20, • \$10 x .20 = \$2.00 • \$10.00 - \$2.00 = \$8.00

5. Please randomly add all of these numbers to your BINGO sheet of paper. • \$71.20 • \$17.80 • \$53.04 • \$4.04 • \$47.70 • \$2.70 • \$10.60 • \$.60 • \$50.00 • 149.99 • \$162.36 • \$9.20 • \$239.19 • \$.74 • \$158.99 • \$189.99

6. The object of the game: • Solve each math problem from the PPT. • Cross out the answer on the bingo card. • The first three students with four in a row win!
