  5. Calculating Sales Tax • Sales tax is calculated by multiplying the • retail price of an item by the sales tax rate. • METHOD 1 • Example: Shoes $100 • Tax Rate 7% Sales Tax $100 x 0.07 = $7.00 Total Purchase Price $100 + $7.00 = $107

  6. Calculating Sales Tax • Sales tax is calculated by multiplying the • retail price of an item by the sales tax rate. METHOD 2 • Example: Shoes $100 • Tax Rate 7% • Add 7% to 100% since that includes the total price and the tax.Find 107% of $100. = $107 Find total $100 x 107% Multiply $100 x 1.07 Both methods give you the same answer!

  7. Calculating Sales Tax A family purchased a pool table for $825. The sales tax rate was 7%. What was the total cost? Method 1 Add sales tax to the price: $825 x 7% = tax $825 x 0.07 = $57.75 $825 + $57.75 = $882.75 Method 2 Multiply the price by 107% since 7% is added to the cost. $825 x 107% = total cost $825 x 1.07 = $882.75 So, the total cost of the purchase was $882.75.

  8. Leaving a Tip As a courtesy it is always nice to leave a tip when someone does something nice for you. Many different types of professions work for tips A pizza delivery man A waiter or waitress A hairdresser or barber Usually the amount of tip depends on how well you think the service was.

  9. Leaving a Tip If you get really good service at a restaurant it is usually due to having a good waitress. A good tip for a waitress is 18%. If the service was not as well as you liked then you can leave a smaller tip such as 10% or 5%.

  10. Leaving a Tip You and a friend go to lunch. The check comes to $24.85. Figure out how much you should tip if you want to leave 15%. Make an estimate first using benchmarks. Find 10% of 25 = $2.50 Then Find 5% of 25 = $1.25 = $3.75 An estimate for the tip is about $3.75

  11. Leaving a Tip You and a friend go to lunch. The check comes to $24.85. Figure out how much you should tip if you want to leave 15%. Now solve using a calculator. Find 15% of 24.85 Change 15% to a decimal = 0.15 x 24.85 = $3.7275 Put your answer in a sentence: The tip should be $3.73 (is that close to our estimate of $375?)

  12. Whiteboard practice. • Find the tax on an item that costs $54 if the sales tax rate is 8%. 2. What is the total price including the tax? 3. Find the tax on an item that costs $40 if the tax rate is 9.25%. 4. Find the total price including the tax. 5. ESTIMATE: A 15% tip on a meal of $48.89.

  13. REMEMBER:To Always Show Your Work • Take out your Learning Targets!

  14. LT #10 Sales Tax A family purchased a DVD player for $200. The sales tax rate was 7%. What was the total cost of the purchase? Method 2 Multiply the price by 107% since 7% is added to the cost. $200 107% = total cost $200 1.07 = $214.00 Method 1 Add sales tax to the price: $200 7% = tax $200 .07 = $14.00 tax $200 + 14.00 = $214.00 So, the total cost was $214.00.

  15. LT #11 Tips Mrs. Girt earned average tips of 18% while waiting tables at Denny’s. If her sales one night were $730, what did she make in tips? 2 730 x 0.18 Tips = 0.18 730 $131.40 = 1 5 8 4 0 7 0 3 0 3 1 1 4 0 Mrs. Girt earned $131.40 in tips that night.

  16. Tips LT #11 The dinner bill at Olive Garden was $58.57 cents. If your family wanted to leave a 15% tip for the waiter approximately how much should they leave? Tip = 15% of $58.57 Kind of an “ugly” calculation! Tip = .15 58.57 SO: Use Benchmarks and Short cuts to estimate tip: Round $58.57 to $60 then take 15% by using 10% + 5% to get the tip. 10% of $60 = $6 + 5% of $60 = $3 15% of $60 = $9 So the tip should be about $9.
