## Math Percentage Question Seeking Solution

Okay, when I began baking I didn't expect to have to remember my college algebra but little did I know what was awaiting me.

Question:

I have 150g of starter at 75% hydration.

I want to know what the formula is that I can apply to determine the weight of the flour and the weight of the water included in that 200g.

If I was working with a 100% starter the solution would be a snap.

But with this I have tried applying all the formulas I know and the only way I can come up with an answer is to do my 'hit and miss' method of math....I find a number less than 200 but greater than 100 and multiply it by 75% until I hit upon the correct combination.

I know there has to be a more direct path but when a problem calls for more than one unknown - I am lost.

So far all I can come up with in a way to express this as a formula is: w= (f x 75%): f + w = 200g therefore (f x 75%) + f = 200g. I am at a loss because I don't know what 'f' equals to begin with.... When I try to go any further I get helplessly lost...

Anybody have a SIMPLE formula they would like to share with me????

Thanks,

Janet
