\n" ); document.write( "----------------
\n" ); document.write( "2t+8c = 445 cents
\n" ); document.write( "t = c + 100 cents
\n" ); document.write( "------------------------------
\n" ); document.write( "Substitute for \"t\" and solve for \"c\":
\n" ); document.write( "2(c+100) + 8c = 445
\n" ); document.write( "-----
\n" ); document.write( "2c + 200 + 8c = 445
\n" ); document.write( "10c = 245
\n" ); document.write( "c = 24.5 cents (price of lb of copper)
\n" ); document.write( "----
\n" ); document.write( "Solve for \"t\":
\n" ); document.write( "t = c + 100
\n" ); document.write( "t = 24.5 + 100
\n" ); document.write( "t = 124.5 cents (price of lb of tin)
