To find how much you will save at a 30% discount on an item listed at $575.50, you can use the formula:

$\text{Discount amount} = \text{Original price} \times \text{Discount percentage}$

Given:

• Original price = $575.50
• Discount percentage = 30% = 0.30

Now calculate the discount:

$\text{Discount amount} = 575.50 \times 0.30 = 172.65$

Thus, the amount you will save is $172.65.

The correct answer is A. $172.65.
