Let the bill amount be $x
\n" ); document.write( "Plan A
\n" ); document.write( "70 + 0.4(x-70)
\n" ); document.write( "Plan B
\n" ); document.write( "130 + 0.2(x-130)
\n" ); document.write( "Plan B < Plan A
\n" ); document.write( "130+0.2(x-130)<70+0.4(x-70)
\n" ); document.write( "130+0.2x-26<70+0.4x-28
\n" ); document.write( "0.2x>130-70-26+28
\n" ); document.write( "0.2x>62
\n" ); document.write( "/0.2
\n" ); document.write( "x>310
\n" ); document.write( "The bill amount should be greater than $310
