Rephrase: what is 35% of $120?
Alex777 [14]

Answer:

What is 35 percent off 120 dollars?

Step-by-step explanation:

Thus, a product that normally costs $120 with a 35 percent discount will cost you $78.00, and you saved $42.00. You can also calculate how much you save by simply moving the period in 35.00 percent two spaces to the left, and then multiply the result by $120 as follows: $120 x . 35 = $42.00 savings.
