You can put this solution on YOUR website!
Plan A = 25 + .05x
\n" ); document.write( "Plan B = 6 + .14x
\n" ); document.write( "At what point will they be equal?
\n" ); document.write( "25 + .05x = 6 + .14x
\n" ); document.write( "Subtract .05x from each side
\n" ); document.write( "25 = 6 + .09x
\n" ); document.write( "Subtract 6 from each side
\n" ); document.write( "19 = .09x
\n" ); document.write( "Divide each side by .09
\n" ); document.write( "x = 211.111111
\n" ); document.write( "Plan B is more advantageous for callers who use 211 minutes or less
\n" ); document.write( "Plan A is more advantageous for callers who use 212 minutes or more.
\n" ); document.write( "
\n" );
