Your first problem seeks to have the gain as the same i.e. 0.35x = 0.25y whereas your second problem seeks to have the total amount the same i.e. 1.35x = 1.25y If we are solving for y then in the first problem y = 0.35/0.25 = 1.4x But in the second problem y = 1.35/1.25 = 1.08x It seems you have a second equation where x + y = 100 So substitute y from your first equation (I'm not sure if you are using problem 1 or problem 2) For problem 1 y = 1.4x x + y = 100 So x +1.4x = 100 2.4 x = 100 x = 100/2.4 x = 41 + 2/3rds which means that y = 58 + 1/3rd For problem 2 y= 1.08x x + y = 100 So x +1.08x = 100 2.08x = 100 x = 100/2.08 x = 48.07692 which means that y = 51.92308 Anyway, I'm not sure if you have expressed your problem sufficiently. Neither of these problems resolves to an answer that can be expressed sufficiently in terms of dollars and cents, problem 1 you need fractions in your answer as you can't express 1/3 as an exact decimal. Problem 2 you end up with decimal points smaller than what can be represented by cents. But anyway, I hope you can follow the workings and know how to apply this yourself (I think you can because your OP shows that you can). And hope you can understand why problem 1 is different from problem 2.

Just say x+y=z for the second equation, solve simultaneously, and you will get x and y as percentages of z (which is what he was looking for anyway). I didn't see this until he gave a specific number for z (100), but it still works without a specific number.

I dunno what equations you're using here, but I'd guess for a basic algebra we're using the compounding interest equation I = p(1+r/n)^nt In this case, and assuming the interest is only compounded once in a single year, there are multiple values which would satisfy this arrangement provided that the first principle is 92.59% the size of the second principle P1/P2 = 0.9259 Unfortunately there is one equation and two unknowns so it cannot be solved for a single value.

RE: Math Problem  help
Pardon me a moment while I think about this.....
X x 35% = z Y x 25% = z let z = $385 (for example) now 385/(35/100) = X and 385/(25/100) = Y so X = $1,100 and Y = $1,540 This is only one example that would work as you propose; there are numerous others. I'm a creationist... I believe that man created God.
