How to pop some tags using
percent, discounts and tax
without leaving your desk!
TAX
• Tax is a percent of the cost of an item that
you must pay, in addition to the item price.
• According to dictionary.com, tax is a sum
of money demanded by a government for
its support or for specific facilities or
services, levied upon incomes, property,
sales, etc.

• When you purchase an item, you must pay sales tax.
• In Brevard County, for example, the sales tax is 6%.
• That means, that in addition to paying 100% of an item, you
also have to pay an additional 6% of that item.
• For example, if a DVD is $10.00, then in addition to you
giving the store $10.00, you will also have to give them 6%
of $10.00, or an additional $0.60, for a total of $10.60.

You want to purchase this brand new Q Piston
watch for your friend’s birthday.
The price is $22.79.
The sales tax is 6%.
$22.79
x 0.06
1.3674 (money rounds to the hundredths place, or $1.37)
The tax then needs to be added back onto the original price.
$22.79
+ 1.37
$24.16
So even though the watch was priced at $22.79, you will need to
pay $24.16 because of the tax.
