To calculate the sale price of a product that costs $65 with a 30% discount, first, you need to determine how much the discount amounts to. This is done by multiplying the original price by the percentage discount:

1. Calculate the discount:

- Discount = Original Price × Discount Percentage

- Discount = $65 × 0.30 = $19.50

2. Subtract the discount from the original price to find the sale price:

- Sale Price = Original Price - Discount

- Sale Price = $65 - $19.50 = $45.50

Thus, the sale price after applying the 30% discount is $45.50, which makes it the correct answer. This approach systematically combines understanding percent calculations with basic arithmetic to arrive at the final price.
