Or, if you want a handy little C program that does all the math
for you...

#include <stdio.h>
#include <stdlib.h>
#include <math.h>

/* takes 3 or 4 floats as arguments, assumes they are: */
/* Population, Industry, Resources, [Stockpile] */
/* and gives: ship mass produceable, capital produceable */
/* written by David Gibbs -- dagibbs@qnx.com  */
void main( int argc, char **argv )
{
	float p, i, r, s;
	float ei, esm, esc;
	float m, c;
	float pi, pf, cp;

if ( (argc < 4) || (argc > 5) )
	{
	  printf("takes three or four floats: Pop Ind Res [Stockpile] \n");
	  exit(-1);
 	}

p = atof( argv[1] );
 	i = atof( argv[2] );
 	r = atof( argv[3] );
 	if (argc == 5)
 		s = atof( argv[4] );
 	else
 		s = 0;

ei = i + (p-i)/4.0;
 	esm = (ei < s*10.0) ? ei : s*10.0;
 	esc = (ei < s*5.0)  ? ei : s*5.0;

m = esm/10.0 + (ei - esm) / (10.0 + 1.0/r );
 	c = esc/5.0 + (ei -esc) / (5.0 + 1.0/r );
 	pi = p*0.08;
 	pf = p*1.08;
 	cp = pi/8.0;

printf("production is: %5.2f mass of ships or %6.2f Capital or %6.2f Tech\n",
 	       m,c, ei);
 	printf("Also produces %6.2f people (total:%7.2f ) or %5.2f colonists\n",
