Price ---------------- quantity
\n" ); document.write( "Coffee Type I $6.00 ---------------- x pounds
\n" ); document.write( "Coffe type II $4.20 ------ 22 - x pounds
\n" ); document.write( "Mixture $5.55 ---------------- 22
\n" ); document.write( " 22
\n" ); document.write( "6 x + 4.2 ( 22 - x ) = 122.1
\n" ); document.write( "6 x + 92.4 - 4.2 x = 122.1
\n" ); document.write( "6 x - 4.2 x = 122.1 - -92.4
\n" ); document.write( "1.8 x = 29.7
\n" ); document.write( "/ 1.8
\n" ); document.write( " x = 16.5 pounds $6.00 Coffee Type I
\n" ); document.write( " 5.5 pounds $4.20 Coffee type II
