Final answer:
The sale price of the item is $20.40, calculated by converting the 30% sale discount to a decimal (0.30) and multiplying it by the original price of $68.
Step-by-step explanation:
To find the sale price of an item that costs 30% of the original price, we need to first convert the percent to a decimal. The original price of the item is given as $68. To convert 30% to a decimal, we divide 30 by 100, which equals 0.30. We then multiply the decimal by the original price to find the sale price.
$68 × 0.30 = $20.40
So, the sale price of the item is $20.40.
