Final answer:
To calculate the retail price after a 28% markdown on an original price of $125, find the markdown amount ($35) and subtract it from the original price, resulting in a retail price of $90.
Step-by-step explanation:
To find the retail price after a markdown, you would subtract the markdown percentage from the original price. In this case, the original price is $125, and the markdown is 28%. First, convert the markdown percentage to a decimal by dividing by 100, which is 0.28. Then multiply this decimal by the original price to find the amount of the markdown:
Markdown amount = Original Price × Markdown Percentage = $125 × 0.28 = $35.
Next, subtract the markdown amount from the original price to find the retail price:
Retail Price = Original Price - Markdown Amount = $125 - $35 = $90.
Therefore, the retail price after the markdown is $90.
