Answer:
A. $42.67
Step-by-step explanation:
1. "Markup" is defined as the amount by which the selling price of an item is increased above its cost to the retailer. (Source: BusinessDictionary.com)
2. The formula for calculating markup is: markup = (selling price - cost) / cost. (Source: Investopedia)
3. To find the cost of an item to the retailer, we can use the formula: cost = selling price / (1 + markup). (Source: Khan Academy)
Now, let's work through the problem using these formulas:
1. First, we know that the original price of the hand-held music player was $66.00.
2. Next, we know that the item was marked up by 1/2 before it was placed on the sales floor. This means that the markup is 1/2, or 50%.
3. To find the cost of the item to the retailer, we can use the formula: cost = selling price / (1 + markup). In this case, the selling price is $66.00, and the markup is 50%, so:
cost = $66.00 / (1 + 0.5)
= $66.00 / 1.5
= $42.67
