I know the answer, I just don’t understand why they got what they got.

Employees at Taylor’s Music Mart get a 20% discount on all purchases. If Brandon buys 3 CDs at $9.99 each, what will he have to pay after his employee discount.

The answer that shows up in my book is .80 x 3 x 9.99 = 23.98

My question is how did they get .80? If you could give me a step by step as to how you solve the problem, that would be great.

Thanks!

## Percent Word Problem, 10 Points To Best Answer!?

December 3rd, 2012 admin

You could (as most books and teachers teach) find 20% of the price

and then do a subtraction problem to find how much you will pay.

BUT THINK……If you are NOT going to pay 20% of a value then

you ARE going to pay 80% of the value.

What you are doing is Subtracting first (100% – 20% = 80%) and then

multiplying by .80 as opposed to multiplying by .20 and then subtracting.

Let me know if I can be of further help….

Let me know if you have questions on this problem or any other math problems.

I am an excellent math teacher/tutor specializing in making students

faster…..smarter……and better looking like myself. Okay, just faster and smarter

….you don’t want to look like me. I TUTOR FREE ONLINE VIA SKYPE.

Keeps me busy since moving from Florida to France. I make C, D , F students

The 20% discount means they DO NOT have to pay 20% of the original cost, so they DO have to pay 80% of the original cost, because 100% = 20% + 80%, or 1 = .20 + .80. Does that help?
