What is the percentage markup if a retailer sells a product for $9 after buying it for $6?

To determine the percentage markup, you can use the formula for markup percentage, which is calculated as the difference between the selling price and the cost price, divided by the cost price, and then multiplied by 100 to get the percentage.

In this scenario, the product is purchased at $6 and sold for $9. First, calculate the markup amount by subtracting the cost price from the selling price:

Selling Price - Cost Price = $9 - $6 = $3

Next, divide the markup amount by the cost price:

Markup Amount / Cost Price = $3 / $6 = 0.5

Finally, to convert this figure into a percentage, multiply by 100:

0.5 × 100 = 50%

Thus, the percentage markup is 50%. This shows that the retailer increased the price of the product by 50% over the cost price, reflecting how much more the selling price is compared to what was originally paid for the product.
