You would calculate $100*(0.33)=$33, then you would go: $100-$33=$67. $100 would be the original price, $33 would be the amount off, $67 would be the new price.
Note:
* this denotes a muliplication action.

Every percentage question uses the exact same equation, which looks
like this:
part percentage
------- = ----------
whole 100
Any percentage problem will give you two of the three unknowns, and
then you just have to rearrange the equation to get the other one.
And since there are only three unknowns, there are really only three
kinds of questions that anyone can possibly ask:
1. What is ___ percent of ___?
(Given whole and percentage, find part)
2. ___ is what percent of ___?
(Given part and whole, find percentage)
3. ___ is ___ percent of what?
(Given part and percentage, find whole)
Here is an example:
36 is what percent of 150?
I've been given the part and the whole, so I set up my equation:
36 ?
--- = ---
150 100
Then I rearrange it, and reduce it:
100 * 36 2 * 50 * 3 * 12
? = -------- = ---------------- = 24
150 3 * 50
Here is another example:
25 is 40 percent of what?
I've been given the part and the percentage, so I set up my equation:
25 40
-- = ---
? 100
Then I rearrange it, and reduce it:
25 * 100 25 * 2 * 5 * 10 125
? = -------- = --------------- = --- = 62.5
40 2 * 2 * 10 2
Here is another example:
What is 35 percent of 90?
I've been given the whole and the percentage, so I set up my equation:
? 35
-- = ---
90 100
Then I rearrange it, and reduce it:
90 * 35 9 * 10 * 7 * 5 63
? = -------- = -------------- = ---- = 31.5
100 2 * 5 * 10 2
or The easy way
Just put a decimal in front of the number
33% would be .33
then multiply
100x.33= 33.33
But if get a single digit percentage you will add a 0 in front
5% would be .05
then multiply
100x.05= 5
Hope it helped oh yeah i almost forgot.if using a calculator do it like this
100x 5 then hit the % button

33% is 33rds of 100 so if you subtracted 33 from 100 what would you have?
