What is marked up and marked down price?

Markup refers to the value that a payer adds to the cost price of a product. The value added is called the mark-up. The mark-up added to the cost price usually equals retailprice.

Markdown represents the difference between the original or full price of an item and the current price that's reduced. It's typically expressed as a percentage. Markdown allows retailers to sell their products at a lower rate.

Given, A hand-held digital music player was marked down by 1/4 of the original price.

Let the original price be x.

Then discount = x/4

So, Sale price = x- x/4 = 3x/4.

A. sale price given = $128

⇒ 3x/4 = 128

⇒ x = 128 × 4/3

⇒ x = 512/3 = 170.67

The original price $170.67

B. The item was marked up by 1/2 before it was placed on the sales floor.

then cost = $170.67 + $170.67 × 1/2

cost = $ 170.67 + $85.335

cost = $256.005 = $256

C. Difference between the discount price and price the store paid for the digital player

= cost - sales price = $256 - $128

= $128

Hence,

A. $170.67 is the originalprice of the digital music player.

B. Store paid price of $256 before it was placed on sales floor.

C. There was difference of $128 between discount price and the price store paid for the digital player.

It was marked down 1/4 of the original price to $128. That means $128 is equal to 3/4 of the original price. So the original price would be 4/3 of $128. I get $170.67 (rounded to the nearest cent).

To create a poster with dimensions 13x13in, you will need to make multiple enlargements using the given settings. You will need approximately 1 enlargement.

To create a poster with dimensions 13x13in from a square picture with dimensions 6x6in, you will need to make multiple enlargements or reductions using the given settings. Since the desired dimensions are larger than the original picture, you will need to use the enlargement setting. The enlargement factor given is 140%, which means you need to increase the dimensions of the picture by 140%. Here's how many enlargements you will need:

1. Calculate the growth factor by subtracting 100% from the enlargement factor: 140% - 100% = 40%
2. Calculate the number of enlargements needed by dividing the growth factor by the enlargement factor: 40% / 140% ≈ 0.2857 (rounded to 5 decimal places)

Therefore, you will need to make approximately 0.2857 multiple enlargements, which can be rounded to 0.29 or 1 enlargement.
