Tax
Sales Tax is the amount you pay for tax after a
purchase.
Sales tax is the percentage of the purchase cost
that the tax rate is.
5.00 X 0.06 0.30
If the sales tax says 6, that means 6 of what
ever the customer pays for the item.
You would then multiply the tax rate by the full
cost without tax.
So, if the normal price is 5.00, and the tax
rate is 6, you multiply 5.00 by .06. (The tax
rate)
Then add the product (0.30) to the full normal
price. Then you have the full price.

Discounts
The discount is the amount, if there is a sale or
discount, that is taken off the full price before
tax.
To find the discount price, it is similar to the
sales tax.
If the discount is 25 off and the normal cost is
20.00,you would then multiply 0.25 (25) by
20.00.
0.25x20.005.00
Then subtract the product from the full price
(20.00) to get the discount cost of 15.00. Then
you would find the tax like in the previous slide.

Simple Interest
If the amount is 200.00 and the interest rate is
6, multiply 200.00x.0612.
Simple interest is the amount added to your bank
over time. So if you had 200.00 in your bank,
after one year you may have 208.89 in your
account.
200.00x.0612
Then add the product to the original amount. So
200.0012212.00. Which is what the amount in
your account would be.
To find the interest, you must multiply the
amount in your bank account by the interest rate.
