I have a number such as 644.02. I need to develop a formula that will give
the result of all possible numbers that divide into it that have a sum that
results in an even number. This is a dollar amount that equates into postage
applied to envelopes or flats. I need to find out the possiblilities of what
rate was used on all pieces of mail, it will come to an even piece count once
I find that rate. Example:
$240 would come out to 400 pieces of mail at a rate of .60. With only one
known variable is there a way?
