where do u get the 1.1 from?
2007-02-11 15:38:50 · update #1
Think of it this way. If Sandy got a 10% raise, what she's currently making, i.e., $396, is 110% of her original salary. First, according to the rules of algebra, the word "of" is equivalent to "x (multiplication)."
So: let's, for brevity's sake, call Sandy's original salary "n."
According to our previous conclusions,
$396=110% x n [110% = 1.10]
$396 = 1.10n
Divide 1.10 from both sides
$360 = n
Sandy's original salary was $360
Proof.
360 x 10% = 360 x .1 = $36
10% of $360 is $36
$360 + $36 = $396
Hope this helped

396 = old salary + 10% of old salary . lets call old salary "s".
so (old salary) s = 396 - (1/10 s (10%) )
add 1/10 s to both sides
s + 1/10s = 396 or, written differently 1 1/10 s =396
1 1/10 in decimal is 1.1 so 1.1s = 396
Divide both sides by 1.1 gives s (old salary) = 396 / 1.1
Which equals $360
To check your answer : 360 + 10 % 360 (which is 36) = 396.

396 divided by 110% == 360
360 x 10% = 36
360 + 36 = 396

396/1.10 take her current salary and divide by 1.1 because her salary increased by 10% thus you add the .1 to 1 which represents her old salary
396/1.1 = 360 her old salary
as proof take 10% of 360 which is 36 and add it to 360
360+36 = 396
DONE

x * 1.1 = 396
x = 396/1.1
x = 360
You use 1.1 because 1 is 100%. ie. 1*396=396. And 0.1 is 10%.

396 / 1.1 = 360
She now gets 110% of her previous salary so in decimal that's 1.1

356.4
Find 10% of 396. Then subtract that from 396 to find the amount prior to her raise.

it is the most direct way: % enhance = [(New earnings/previous earnings) - a million] x one hundred% % enhance = [($389/$351) - a million] x one hundred% % enhance ? (a million.1083 - a million) X one hundred% % enhance ? 0.1083 x one hundred% % enhance ? 10.80 3%. we may be able to educate that it is an similar because the more beneficial commonplace attitude to calculating an enhance: % enhance = [(New earnings - previous earnings)/ previous earnings] x one hundred% % enhance = [($389 - $351)/$351] x one hundred% % enhance = ($38/$351) x one hundred% % enhance ? 0.1083 x one hundred% % enhance ? 10.80 3%.

110% of X = 396
therefore:
X = 396/ 1.1 = 360
********************UPDATED***************************
You get the 1.1 because 110% equals 110/100...break that down and you get 1.1
