Numbers with two decimal points scare me. Whatever the original price was, multiply it by 0.3 to find out how much you'll save. Multiply it by 0.7 to find out the new price.
you have to multiply both numbers then by a 100 to get your answer -_______-
Step 1: Take the old value and subtract it from the new value, then divide by the old value. Step 2: Multiply by 100. That number represents the percent change.
Convert the discount into a decimal equivalent by removing the percent sign and placing the decimal 2 places to the left of the number in front of the percent sign. (25% = .25; 5% = .05, etc.). Then multiply the number that you want to find the discount for by the decimal equivalent. Example: to find how much 250 with a 15% discount is, multiply 250 x .15 (250 x .15 = 37.50).
Yes. To determine the discount of 10%, move the decimal one space to the left. That will be the 10% discount. So if you're looking at a $100.00 item, the discount would be $10. If you're looking at a $79.85 item, the discount is $7.985 (or roughly $8.00).
Multiply the price by 0.2 to get the amount of the discount. Multiply the price by 0.8 if you want to know the after sale price.
The quickest way is to multiply the full price by 0.2 That is the amount of the discount.
I always use a factor of ten. Assume no matter what the discount is it is ten percent to find a ten percent discount just move the decimal point one space to the left, then take that number and subtract it from the original cost. Then in order to find a different percent discount just multiply the ten percent discount by the percent discount you are looking for, but move the decimal one space to the left again, and subtract that from the original cost. Example: something that costs $45 is on sale for 25% off. A ten percent discount would be $4.50. Multiply that by 2.5 to get$11.50. Then subtract that from the original cost to get $33.50. P.S. often times if you don't need the exact answer it is easier to round you numbers to get rid of the .5 to make the math easier.
How to calculate sale price if marked price and percent discount are given:First change the percent discount to a decimal.You then multiply the percent discount in decimal form by the marked price.Finally, you subtract the answer from the multiplication problem from the marked price, and get your final answer!
To find the discount of something, you need to take whatever percent the discount is, turn it into a decimal, and multiply it by the price of the discounted item. Example: You want to buy something that is $10.00 The item has a 25% discount. take 10 and multiply it by .25 Discount: $2.50
To determine what 25 percent of a number is, multiply the number by 0.25
All you need to do to calculate percentages is multiply the decimal form of the percent to any number. In this case, you would multiply 0.3 by 47.5 and get 14.25.
Discount divided by original price gives you a decimal which you then multiply by 100. This equals percent of discount Eg: $15 discount, $80 original price 15 / 80 = 0.1875 x 100 = 18.75%
Take your number and multiply by .85
Numbers with two decimal points scare me. Whatever the original price was, multiply it by 0.3 to find out how much you'll save. Multiply it by 0.7 to find out the new price.
Take the amount saved, divide it by discount percentage then multiply the result by 100.
If your item is 50 dollars and the discount is 10 percent, you can divide 50 by 10 which would be five dollars off. It the discount is 20 percent, you can take 5 times 2 which would be 10 dollars off. Always begin by figuring out a 10 percent discount and multiply from there.
