How do you calculate percentage off?

3. Employees of a discount appliance store receive an additional 20% off of the lowest price on an item. If an employee purchases a dishwasher during a 15% off sale, how much will he pay if the dishwasher originally cost $450?



Can someone show me the step by step as to how to solve this? Thank youHow do you calculate percentage off?
There could be 2 possibilities for this answer.

could be done the way it is listed above or it

can be done this way if the discounts are not

allowed to be combined. the above way works well

for the consumer and the below way works best for

the the corporation.



in conclusion you convert the percentile into a

decimal and multiply by the actual cost to get the

discount.





$450 - 15%($450 x .15= $67.50) = $382.50



$382.50 - 20%(382.50 x .20= $76.50) = $306



That would be $144 off the original price.How do you calculate percentage off?
If the employee gets the discount AFTER the lowest price, then you would want to calculate the 15% off first.



Percentage is calculated as such:



15% is just a number like this: 15.00



Move the decimal point two spaces to the left so that you get .15, then multiply 450 by .15.



The number you get (I'm not telling you the answer, lol) is the amount you should subtract from $450 (that is, $450 - answer = new amount).



You should then use the same process with the 20%, only taking it off the new amount you got after determining 15% off (that is, new amount X .20 = percentage off).



Finally, subtract the percentage off from the second amount and you'll have your answer.



Another way to look at it:



$450 x .15 = b



$450 - b = c



c x .20 = d



c - d = e



e is final answerHow do you calculate percentage off?
20%+ 15% = 35%

100%= $450

35%= ?



35 x 450= 15750

15750/ 100 = 157.5 off

450- 157.5= 292.5
