Final answer:
To find the cost of an item with a 35 percent discount, multiply the marked price by 0.65.
Step-by-step explanation:
To find the cost of an item that was marked x dollars with a 35 percent discount, we can multiply x by 0.65. This is because a 35 percent discount is the same as paying 65 percent of the original price. So the cost of the item would be x multiplied by 0.65, or 0.65x dollars.
