Question: what is 40 of 30 dollars?
Answer: Thus, a product that normally costs $30 with a 40 percent discount will cost you $18.00, and you saved $12.00. You can also calculate how much you save by simply moving the period in 40.00 percent two spaces to the left, and then multiply the result by $30 as follows: $30 x . 40 = $12.00 savings.
