need a math expert me to help write this forwula for excel
1000((value from cell)+.256)=(((x+.314)1000)+9)1.0625
I would like to plug in a value from a cell and find the comparative value x
I am comparing the airfregiht cost between two carriers that have different surcharges for fuel, secuirty, and tax. One has no security or tax.

Re: Write This Formula
Assuming I solved correctly for x, I think the formula you want if you enter your cell (known) value in A1 is
=(((1000*A1+0.256)(9*1.0625))/(1000*1.0625))0.314
EDIT: And ... I forgot to say Welcome to OzGrid

Re: Write This Formula
Thanks for the quick reply,
The formula isn't producing the correct results. Its been over thirty years since I graduted college. Just can't remember how to do the math. Would you look at it again.
Here's the deal
1000 kg of airfreightA1 rate is a per kilo rate plus fuel surcharge of $0.256 per kilo
X is a competitor's rate per kilo but the fuel surcharge is $0.314 per kilo plus a flat $9.00 fee all taxable at 6.25%.
I am trying to write an excel formula to find the value of x to match a1 rate.

Re: Write This Formula
You seem to have two unknowns, with no given connection between them...
EDIT: Ah, I think I see what is needed is a ratio, not a value.

Re: Write This Formula
I believe tomach is on the right track but has inadvertantly left out one set of brackets...
The order of math opperations is * / before + 
so =1000*A1+0.256 will multipy 1000*A1 and then add .256
where 1000*(a1+.256) is what you are looking for
=(((1000*(A1+0.256))(9*1.0625))/(1000*1.0625))0.314
