You can put this solution on YOUR website!
You have two payment options
\n" ); document.write( "\"c+=+42+%2B+0.14m\" and \"c+=+84+%2B+0.07m\"\r
\n" ); document.write( "\n" ); document.write( "You are asked to find out at which point the two options cost the same. \r
\n" ); document.write( "\n" ); document.write( "\"42+%2B+0.14m+=+84+%2B+0.07m\"
\n" ); document.write( "\"0.07m+=+42\"
\n" ); document.write( "\"m+=+600\"
\n" ); document.write( "So if you go over 600 miles, the option where miles cost 7 cents apeice, will result in a lower total cost.\r
\n" ); document.write( "\n" ); document.write( "Graphically, the line that is 'above' the other line at any specific mileage is the more costly option\r
\n" ); document.write( "\n" ); document.write( "\"graph%28600%2C400%2C-100%2C900%2C+-100%2C+200%2C+0.14x%2B42%2C+0.07x%2B84%29\"
\n" ); document.write( "
