Sales tax

Sales tax is an additional amount of money charged on items that people buy. The total cost of an item is the regular price plus tha sales tax.

A DVD player costs $120 and the sales tax is 6%. What is the total cost of the DVD player? Step 1: Find the sales tax  6% of$120 = 0.06x120 Write 6% as a decimal = 7.2 The sales tax is $7.20 Step 2: Add the sales tax to the regular price.$7.20 +$120=$127.20

The total cost of the DVD player is $127.20. What is the total cost of a sweatshirt if the regular price is$45 and the sales tax is 7%

Step 1: Find the sales tax

 7% of $45 = 0.07x45 Write 6% as a decimal = 3.15 The sales tax is$3.15

Step 2: Add the sales tax to the regular price.

$3.15 +$45=$48.15 The total cost of the sweatshirt is$48.15.
