1. Discounts\Sales

2. Percents are used every day
We know that we have to pay 13% (in N.B.) sales tax.
Often we find things “On Sale.”
Sales are usually expressed as a “ percent off”
To find the amount of the discount or price we have to pay, we have to use percent.

3. Finding a Percent Discount
A coat is regularly priced at $125.
It is on sale for 30% off.
Three questions:
1. What is the amount of the discount?
Estimate first. (Think 10 % is 12.50, so 30% would be around $37).
What will you have to pay for it on sale?
How much will you have to pay with the sales tax (13%) added?

4. 1. How much is the discount
The question is – What is 30% of 125

5. What is the Sales price?
Subtract the discount from the original price.
Original price – discount = sales price
$125 – $37.50 = $ 87.50

6. Final Price at cash register
The question is What is 13% of the sales price?
.13 x $87.50 = $11.38
Add the tax to the sales price to get the final price.
Sales price + tax = total price of coat
$ $11.38 = $98.88
