Discount and Markup

To find the discount and markup, you do one simple operation: Multiply.

The only thing that is different is the next step: Finding the sale price vs. finding the selling price after the markup

Sale Price:
1. Multiply the original price by the percent of discount (don't forget to move the decimal over twice first!)
2. Subtract (think ¨Sale Subtract) the discount from the original price.


Markup:
1. Multiply the original price by the percent of markup (don't forget to move the decimal over twice first!!)
2. ADD (think MArkup - Multiply, Add) the markup price to the original price.

You should get a cheaper cost for the SALE price and a higher cost for the new SELLING price (after markUP).


Example:

1. A $30 sweater is 30% off. Find the sale price.

Step One: Multiply $30 by 0.30 = $9.00.
Step Two: Subtract (think SALE-SUBRACT) 30 - 9 = $21.

You save $9.00 and only pay $21 for the sweater after the discount.


Example:

2. A computer store buys a computer for $120 and markups the price by 20%. Find the new selling price.

Step One: Multiply $120 by 0.20 = 24 ($24.00)
Step Two: Add (think MArkUP - Multiply, Add) 120 + 24 = $144.

The computer store will charge $144 to the customers after the markUP.
