I have a little trick for percentage. Since it is 30% just take 10% off 6.00 and multiply that by 3. So here is how I would do it:
10% of 6.00 is .60 because with 10% you just take one zero off.
Next you do:
.60 x 3 = $1.80
After that, you would simply do:
$6.00-$1.80 and get $4.20

1. Change the percentage to a decimal = .30
2. Multiply it times the $ amount
$6.00 x .30 = $ 1.80

3. $1.80 is the percent off.
4. Subtract if you need to find out what the final cost is.
$6.00 - $1.80 = $4.80

GOOD LUCK, HOPE YOU GET AN A!!!!!

It's $1.80.

Here's how I do this kind of quick mental math.

10% of $6.00 is 60 cents. Just move the decimal.

30% means that it's 60 cents times 3 - 6 times 3 is 18 - so the discount is $1.80.

If it was a 25% discount, I'd start with 60 cents, double it - $1.20 - and then tack on an additional 30 cents (5% of $6.00.)

It feels confusing, but it you break it down to tens, I find you can figure it out pretty quick after a while.

Find the amount when the base and percent are known.

Convert 30 % to decimal

Remove the % symbol. Divide 30 by 100

30 / 100 = 0.3

Multiply 6 times the decimal

6 x 0.3 = 1.8

The amount is $ 1.80

$ 1.80 is 30% of $ 6.00

I'll simply approach with one simple operation. are you ready?

30% off means 70% only you have to pay, got me?

So 70% of 6.00 $ is = 6.00 $ x 0.7 = 4.20 $

Further: percent means 100/100 which is equivalent to one (1.0) in decimal number.
therefore, 10 % means 1/10 or 0.10 so the opposite or balance is 90% or 0.90 (the decimal equivalent, which is more simple to calculate, you need not to use subtraction as the second simplifying final solution).

Example: 10% off of 6.00$ the opposite or balance is 90%
Solution: 0.90 x 6.00$ = 5.40 $

Simple because it is just 1 to 10 ( times 10) , so 10 to 100.

6 x 30%= 6 /1 x 3/10 or 6 x .30= 1.80

Easiest way is to just multiply $6.00 by 0.7. This gives you 70% of the original value, which is obviously 30% off.

$6.00 x 0.7 = $4.20

ALWAYS READ THE QUESTION CAREFULLY!!

Numerous people here have said $1.80, which is wrong, since it says "30% OFF of $6.00", not "30% of $6.00"

Another way of looking at it

If you have 30% off then 70% remains so final price is 70/100 x 6.00 = 4.2

The French word for 100 is "cent". The word "percent" means "per 100". So if you get any fraction, like 1/2, and you are asked to express it as a percentage, you need to think in terms of 100.

For example, if somebody says to you: "One half of the gang members carry guns" just as yourself, "How many would carry guns if there were 100 gang members?" The answer will be the "percent" of gang members who carry guns.

Similarly, if you see "30% off of $6.00" it really means

30/100 (30 per hundred) off of $6.00

Just multiply $6.00 by 30/100

The answer is?

I'll leave it for you to do the math.
