C(m) = .5(m - 100) + 20, with m ≥ 100
\n" );
document.write( "C(m) = .5m - 50 + 20, with m ≥ 100
\n" );
document.write( "Correct equation: , with m ≥ 100
\n" );
document.write( "Changing the equation's variables for graphing. we get:
\n" );
document.write( "                    , with, m ≥ 100 ------ Replacing cost, based on minutes, or C(m), with y, and m (minutes) with x.
\n" );
document.write( "                    Now, YOU do the graphing. \n" );
