that's exactly how i do it now. I think that's the best logicirock wrote:let X be the cost of dinner without the tip.
so total cost= x+0.15x=230
ie, 1.15x=230 ==> x=200
Hence dinner is $200.

Dinner cost $230 including a 15% tip.
How much was dinner without the
tip?
My answer is 195.5
OA is
Answer: $200
If $230 includes the cost of the dinner plus an additional
15%, then it is 115% of the cost of the dinner, so 230 =
(115/100)x.
x 200 = x[/spoiler]

Exp. Question
I found this on a GMAT website and I'm pretty sure it's wrong:
(-2)^-3 = 8
shouldn't this be -1/8?
Here is the link; it's point #9

I know this sounds silly but I'm missing the last step?aatech wrote:#-7# = a*-7*3 + b*-7 - 1 = 3
=> -21a-7b-1=3
=> 21a+7b=-4 -----(1)
#7# = a*7*3 + b*7 - 1 => 21a+7b-1 ---(2)
Replacing value from (1) to (2) we get -5
What exactly happens when you replace terms?
