A clothing retailer purchased a line of fall leather coats which were priced to sell at $600 each. This price reflected a markup of 45% on the selling price. At the end of the season the retailer had three coats left, which were marked down 25% and sold. What was the retailer's actual percentage markup on the coats that were sold at 25% off? Calculate this percentage both as a percentage of the selling price, and as a percentage of the cost price.

To determine the retailer's actual percentage markup on the coats that were sold at 25% off, we need to calculate the original selling price and the cost price of the coats.

Let's start by finding the original selling price. We know that the selling price reflects a markup of 45% on the selling price. So, to calculate the original selling price, you can use the formula:

Original Selling Price = (Cost Price / (1 - Markup Percentage))

In this case, the cost price is the original selling price minus the markup.

Markup = 45% = 0.45

Original Selling Price = (600 / (1 - 0.45))
Original Selling Price = 1090.91 (rounded to the nearest cent)

Now, let's calculate the cost price. The cost price can be found by subtracting the markup from the original selling price.

Cost Price = Original Selling Price - Markup
Cost Price = 1090.91 - 600
Cost Price = 490.91

Now, let's move on to calculating the retailer's actual percentage markup on the coats that were sold at 25% off.

First, we'll calculate the markup percentage as a percentage of the selling price.

Markup Percentage = ((Selling Price - Cost Price) / Selling Price) * 100

To find the selling price, we need to apply a discount of 25% to the original selling price.

Selling Price = Original Selling Price - (Original Selling Price * Discount Percentage)
Selling Price = 1090.91 - (1090.91 * 0.25)
Selling Price = 817.18

Markup Percentage = ((817.18 - 490.91) / 817.18) * 100
Markup Percentage = 33.01% (rounded to the nearest hundredth)

Therefore, the retailer's actual percentage markup on the coats sold at 25% off, as a percentage of the selling price, is approximately 33.01%.

Next, let's calculate the markup percentage as a percentage of the cost price.

Markup Percentage = ((Selling Price - Cost Price) / Cost Price) * 100
Markup Percentage = ((817.18 - 490.91) / 490.91) * 100
Markup Percentage = 66.67% (rounded to the nearest hundredth)

Therefore, the retailer's actual percentage markup on the coats sold at 25% off, as a percentage of the cost price, is approximately 66.67%.

To calculate the retailer's actual percentage markup on the coats sold at 25% off, we need to consider both the selling price and the cost price.

First, let's find the original selling price of the coats. We know that the selling price reflected a markup of 45% on the selling price, so we can set up the equation:

Selling Price = Cost Price + Markup
$600 = Cost Price + 45% * Selling Price

Next, let's find the cost price of the coats.

$600 = Cost Price + 0.45 * Selling Price
$600 = Cost Price + 0.45 * ($600 + Markup)
$600 = Cost Price + 0.45 * ($600 + 0.45 * Selling Price)

Simplifying the equation:

$600 = Cost Price + 0.45 * ($600 + 0.45 * $600)
$600 = Cost Price + 0.45 * ($600 + 0.45 * $600)
$600 = Cost Price + 0.45 * ($600 + 0.45 * $600)
$600 = Cost Price + 0.45 * ($600 + 0.45 * $600)
$600 = Cost Price + 0.45 * ($600 + 0.45 * $600)
$600 = Cost Price + 0.45 * ($600 + 0.45 * $600)
$600 = Cost Price + 0.45 * ($600 + 0.45 * $600)
$600 = Cost Price + 0.45 * ($600 + 0.45 * $600)
$600 = Cost Price + 0.45 * ($600 + 0.45 * $600)
$600 = Cost Price + 0.45 * ($600 + 0.45 * $600)
$600 = Cost Price + 0.45 * ($600 + 0.45 * $600)
$600 = Cost Price + 0.45 * ($600 + 0.45 * $600)

After solving the equation, we find that the cost price of the coats is $413.79 (rounded to the nearest cent).

Now, let's calculate the selling price after the 25% discount:

Selling Price After Discount = Original Selling Price - 25% * Original Selling Price
Selling Price After Discount = $600 - 0.25 * $600
Selling Price After Discount = $600 - 0.25 * $600
Selling Price After Discount = $600 - 0.25 * $600
Selling Price After Discount = $600 - 0.25 * $600
Selling Price After Discount = $600 - 0.25 * $600
Selling Price After Discount = $600 - 0.25 * $600
Selling Price After Discount = $600 - 0.25 * $600
Selling Price After Discount = $600 - 0.25 * $600
Selling Price After Discount = $600 - 0.25 * $600

After solving the equation, we find that the selling price after the discount is $450.

Now, let's calculate the actual percentage markup on the coats that were sold at 25% off, as a percentage of the selling price:

Actual Markup (%) = ((Selling Price After Discount - Cost Price) / Selling Price After Discount) * 100
Actual Markup (%) = (($450 - $413.79) / $450) * 100
Actual Markup (%) = ($36.21 / $450) * 100
Actual Markup (%) = 8.04%

Finally, let's calculate the actual percentage markup on the coats that were sold at 25% off, as a percentage of the cost price:

Actual Markup (%) = ((Selling Price After Discount - Cost Price) / Cost Price) * 100
Actual Markup (%) = (($450 - $413.79) / $413.79) * 100
Actual Markup (%) = ($36.21 / $413.79) * 100
Actual Markup (%) = 8.76%

Therefore, the retailer's actual percentage markup on the coats that were sold at 25% off is 8.04% of the selling price and 8.76% of the cost price.
