$title Topbrass example, version 2: upper and lower bounds

option limrow = 0, limcol = 0;

variables x1 'Number of football trophies',

	  profit;

equations obj, plaques, wood;

obj..
  profit =e= 12*x1 + 9*x2;

plaques..
  x1 + x2 =l= 1750;

wood..
  4*x1 + 2*x2 =l= 4800;

model topbrass /all/;

* lower and upper bounds set here
x1.lo = 0;
x2.lo = 0;
x1.up = 1000;
x2.up = 1500;
