You can put this solution on YOUR website!
If we set up 1.59*T + 49.99 = 1*T + 39.99, what do we get for time?
\n" ); document.write( "0.59T = -10
\n" ); document.write( "T = -10/0.59
\n" ); document.write( "---------------------
\n" ); document.write( "If we get a negative number, what does that mean?
\n" ); document.write( "It means there is no equilibrium point (no number of minutes
\n" ); document.write( "when the two plans would have the same charge cost).
