Answer:
In order to calculate the sales tax of an item, we need to first multiply the pre-tax cost of the item by the sales tax percentage after it has been converted into a decimal. Once the sales tax has been calculated it needs to be added to the pre-tax value in order to find the total cost of the item. Let's start by working with an example. If a magazine costs $2.35 and has a 6% sales tax, then what is the total cost of the item. First, we need to convert the sales tax percentage into a decimal by moving the point two spaces to the left.
6%→0.06
Now, we need to multiply the pre-tax cost of this item by this value in order to calculate the sales tax cost.
Round to two decimal places since our total is in dollars and cents.
Last, add this value to the pre-tax value of the item to find the total cost.
$2.49
