Answer: $52.33
Explanation:
Selling Price = $45.50 + (0.15 * $45.50)
Now, calculate the markup:
Markup = 0.15 * $45.50 = $6.825
Now, add the markup to the cost to find the selling price:
Selling Price = $45.50 + $6.825 = $52.325
So, the selling price of the sweatshirt with a 15% markup is approximately $52.33.
