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.

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

How to find the sales tax!

So if an item costs $5.00 Sales tax is 6% Convert 6% to 0.06 So .06 x $5 = $0.31 The sales tax is $0.31 But the total price of the item is

$5.00 + $0.31 = $5.31

How to find the sales tax!

1. Find out the % of the discount. Convert the % to a decimal.

2. Multiply the decimal by the original price.3. Take the answer in step 2 and subtract it

from the original price.Example

1) Discount 20% = .20, 2) $10 x .20 = $2.003) $10.00 - $2.00 = $8.00
