​Discounts and Markups

• ​Discounts are often said as savings, price reduction, markdown, sale, and clearance.

• ​Calculating a discount is like calculating tax, but because you saving money, you subtract it from the original price.

• ​Good luck!

​On the last one, don't forget that the second discount is additional, so it's calculated based on the first discounted price, NOT the original price.

Finding the Original Price

​

​You can also find the original price if you know the final price and the discount.

​First, subtract the percent of the discount from the original cost.

​Two, convert the percent to a decimal.

​Last, solve for the original price.

​Finding the Percent Discount

• ​Similarly (to the last question), you can also find the percent discount if you know the original and final price.

​Markups

• ​Stores often use discounts during sales. But if they did that all the time, they would probably go out of business. In fact stores and manufacturers usually increase their products to make a profit. These increases are known as markups.

​Markups

• ​First, change the percent discount to a decimal.

• ​Second, Multiply the decimal by the original cost. This is the markup.

• ​Then last, add the markup price to the original cost.

• ​Good luck!

​Finding the Original Cost

• ​Just like when you calculate for taxes and fees, you can also find the original cost if you know the final price and the markup.

• ​First, add the percent of the original cost and percent of the markup to get the total cost percent.

​Finding the Original Cost (continued)

• ​Second, convert the percent to a decimal.

• ​And third, solve for the original cost.

​Notice that on the first step of the last question, that you paid the original price plus the store's markup, so the cost of the cake is actually 170% of the original cost.
