Before I start, I'd like to point out that you won't have to do these kinds of calculations on the actual GMAT - EVER!coolgirl26 wrote:friend gave me this problem to solve..very hard for me.

This is a horrible example of an actual GMAT question, clearly it's made up (and poorly).
First equation:
c = 1.5(f - .7) - 1
Second equation:
a = 1.5c + .5
Third equation:
a + c + f = 74.70
Q: f = ?
Let's start by rearranging the third equation:
f = 74.70 - a - c
We have the value for c from equation 1. Plugging that into equation 2, we get:
a = 1.5(1.5(f - .7) - 1) + .5
And substituting for a and c into our final equation:
f = 74.70 - (1.5(f - .7) - 1) - 1.5(1.5(f - .7) - 1) + .5
Some ugly!
f = 74.70 - (1.5f - 1.05 - 1) - 1.5(1.5f - 1.05 - 1) + .5
f = 74.70 - 1.5f + 2.05 - (2.25f - 1.575 - 1.5) + .5
f = 74.70 -1.5f + 2.05 - 2.25f + 3.075 + .5
f = 80.325 - 3.75f
4.75f = 80.325
f = 80.325/4.75
f = 17ish
Again, I can't overemphasize just how non-GMAT this question is - way too many calculations (heck, I may have even made a few small errors along the way, but I'm not motivated enough to check my work!).
