How to pop some tags using percent, discounts and tax without leaving your desk!

#POP-A-TAG#DISCOUNTS

“I’M GONNA POP SOME TAGS” BUT I MIGHT HAVE MORE THAN $20 IN MY POCKET

Thrift shops are great because they sell items that are at a fraction of what they originally cost

SHIRTS This shirt was originally sold for $25.99 at Savalicious Rags.

It is on the rack at the Thrift Shop for $5.

It is a “savings” of $20.99, but that is not the discount. A discount is a percent less than the original cost.

PERCENTS

• The price a customer pays for an item in a store is called the retail price.

• You, as a consumer (person buying from a store), pay the retail price. (In another lesson, you will learn about wholesale and markup)

Retail Price: $15.99 - This is the price the store would like you to pay. It is 100% of the money they would like to make.

100% = $15.99

The reality of retail sales is that many stores carry the same merchandise, and in order for the stores to stay competitive, they need to entice you into shopping at their store, so they offer discounts.

Savalicous Rags runs a full page ad in the newspaper offering 25% off their new white shirts.

There are several ways of finding a price of an item after a discount.

That means, instead of paying 100% of the item, you will not be paying 25% of the item.

100% the whole price of the white shirt- 25% the amount of the white shirt you are not paying 75% the price of the white shirt that you will be paying

If you are not paying 100% of an item, then the price is broken up into two parts:

The part you are paying + The part you are NOT paying

Together they equal 100%

95% 5%

90% 10%

85% 15%

80% 20%

75% 25%

70% 30%

The quicker you are able to relate these numbers, the easier time you will have finding the actual cost to you.

TWO WAYS TO FIND A DISCOUNTED PRICEUSING PROPORTIONS

$15.99 is 100% of the original price

25% discount

Write as a proportion:

=

= To solve for , the variable that represents the unknown price that we will pay, we will find the decimal equivalent of the first ratio, and then multiply it by the whole price. This will create a numerator to be used in an equivalent ratio.

= 0.75 (decimal equivalent)

Calculate 0.75 x 15.99 = 11.9925 (rounds to 11.99)

= 11.99

= $11.99 is 75% of $15.99

IN 1 STEP

$15.99 is 100% of the original price

Find how much of the original price you will pay.

100% of the price - 25% the percent you will not be paying 75% is the amount of the original price that you will be paying

Find the amount of the original price that you will pay:

100% $15.99x75% x 0.75discount price $11.9925

which rounds to

$11.99
