Method 2 Multiply the price by 125% since that is what you ARE paying. $35.50 x 125% = total cost $35.50 x 1.25 = $44.38 Method 1 $35.50 x 20% = $7.10 (tip) $35.50 x 5% = $1.78 (tax) $35.50 + $7.10 + $1.78 = $44.38 So, the total cost was $44.38.

Calculating a Discount Discount is calculated by multiplying the retail price of an item by the discount percentage. METHOD 1 Example: Shoes $50 Tax Rate 25% Discount $50 x 0.25 = $12.50 Total after discount $50 – $12.50 = $37.50

Calculating a Discount Discount is calculated by multiplying the retail price of an item by percent that you will pay. METHOD 2 Example: Shoes $50 Tax Rate 25% Subtract 25% from 100% since that’s what you are paying. Find 75% of $50. = $37.50 Find total $50 x 75% Multiply $50 x .75 Both methods give you the same answer!

Discount A shirt that was $25 is on sale for 20% off. What is the sale price? Method 2 Multiply the price by 80% since that is what you ARE paying. $25 x 80% = total cost $25 x .8 = $20.00 Method 1 Subtract the discount from the price: $25 x 20% = discount $25 x .2 = $5.00 discount $25 - $5 = $20.00 So, the total cost was $20.00.

You Try! A radio that was $120 is on sale for 15% off. What is the sale price? Method 2 Multiply the price by 85% since that is what you ARE paying. $120 x 85% = total cost $120 x .85 = $102.00 Method 1 Subtract the discount from the price: $120 x 15% = discount $120 x .15 = $18.00 discount $120 - $18 = $102.00 So, the total cost was $102.00.
