Need help with a math problem at work. Not sure if I'm posting in the correct area as its been longer than I'd like to admit since I was in college.

This problem deals with agriculture; specifically low cost methods in bulk fertilizer blending for farmers.

I'm trying to find an equation that fits the following problem:

Two constants 21 & 46

What combination of 24.47% will get youequal toorclosest to5.337.

So for example:

21 x 24.00% = 5.04

46 x0.47%=0.21

.......24.47%..5.25

The goal is to find an equation that will find the combination of percentages, who's sum is equal to 24.47%, that will get you equal to or closest to 5.337.

I'm probably not wording it correctly, but its driving me nuts. Any help would be much appreciated.

Thx,

C
