price ---------------- quantity
\n" ); document.write( "Nuts type I 0.8 ---------------- x lb
\n" ); document.write( "Nuts Type II 0.5 ------ 30 - x lb
\n" ); document.write( "Mixture 0.75 ---------------- 30
\n" ); document.write( " 30
\n" ); document.write( "0.8 x + 0.5 ( 30 - x ) = 0.75 * 30
\n" ); document.write( "80 x + 50 ( 30 - x ) = 2250
\n" ); document.write( "80 x + 1500 - 50 x = 2250
\n" ); document.write( "80 x - 50 x = 2250 - -1500
\n" ); document.write( "30 x = 750
\n" ); document.write( "/ 30
\n" ); document.write( " x = 25 lb 0.80 Nuts type I
\n" ); document.write( " 5 lb 0.50 Nuts Type II
