\n" );
document.write( "C=0.4x^2+16x+10  x > 0
\n" );
document.write( "C = .4x + 16 + 10/x 
\n" );
document.write( "C' = .4  - 10/x^2
\n" );
document.write( "   .4 - 10/x^2 = 0
\n" );
document.write( "       x^2 = 10/.4 = 25 
\n" );
document.write( "         x = 5, units that should be produced to minimize the average cost per unit
