I am confused? How do you calculate how much you saved with the percent off?

Thats simple! You would turn 20% into a decimal which is 0.20 and then you would divide that by 5. I am in the sixth grade and we do this all the time!

What you do is this:

Original price - (Original price*percent of discount)

So in your case, the original price was five dollars. The percent of discount was 20%, which is written in an equation as 0.2, because 0.2 is 20% of 1. So here is your equation:

5 - (5*0.2)

Which equals:

5 - 1

Which equals:

4 dollars.

Hope this helped :-)

EDIT: If you just want to find out how much you saved, you do the percent of discount (0.2) times the original price:

5*0.2=1.

EDIT: An alternate method for finding the price after you have received your discount:

(1 - discount)* Original price

Which in you case would be:

(1-0.2)*5

Which equals 4 dollars

:-)

you make the percentage into a decimal. multiply it by the number you are trying to take the percentage of then after you've gotten the answer to that subtract it with the number you are trying to take the percentage of.

so for your situation it would be like this:

$5 × .20= 1.00

5$ - $1 = 4$

so 20% off of 5$ is 4$

20%= .20

5 x .20= Percent you saved. Then subtract it from the total.

5 x .20= 1

5-1=4

Now it costs four dollars.

equation:

0.8 times 5

answer 4$

you get 20 percent out of the one hundred percent

thats where the 0.8 comes from

(1.00 minus 0.20) :

for 5 percent off 95 dollars would be

0.95 times 95
