You can put this solution on YOUR website!
I think you have an incorrect equation because non of your optional answers mahch the equation.
\n" ); document.write( "--------------------------------------
\n" ); document.write( "C(x) = 900 / (x + 30)
\n" ); document.write( "c(x)=900/630
\n" ); document.write( "c(x)=1.428 is the cost per unit.\r
\n" ); document.write( "\n" ); document.write( "c(600)=900/600+30
\n" ); document.write( "c(600)=1.5+30
\n" ); document.write( "c(600)=$31.50 is the cost per unit of plywood.
\n" ); document.write( "
\n" );
