A=total Plan A; B=total Plan B; s=sales
\n" ); document.write( "A=$390+0.07s
\n" ); document.write( "B=$544+0.05s
\n" ); document.write( "A=B
\n" ); document.write( "$390+0.07s=$544+0.05s Subtract $390 from each side.
\n" ); document.write( "0.07s=$154+0.05s Subtract 0.05s from each side.
\n" ); document.write( "0.02s=$154 Divide each side by 0.02.
\n" ); document.write( "s=$7700 Both plans pay the same when sales=$7700
\n" ); document.write( "ANSWER With sales greater than $7700, Chris is better off with Plan A.
