Let \"+x+\" = the number of miles she
\n" ); document.write( "has to drive for the 2 plans to cost the same
\n" ); document.write( "Let \"+C+\" = cost
\n" ); document.write( "For the 1st plan:
\n" ); document.write( "\"+C+=+55+%2B+.5x+\"
\n" ); document.write( "For the 2nd plan:
\n" ); document.write( "\"+C+=+.7x+\"
\n" ); document.write( "----------------
\n" ); document.write( "Make the costs of the 2 plans the same
\n" ); document.write( "\"+55+%2B+.5x+=+.7x+\"
\n" ); document.write( "\"+.2x+=+55+\"
\n" ); document.write( "\"+x+=+275+\"
\n" ); document.write( "Diane needs to drive 275 mi for the two plans to cost the same
\n" ); document.write( "-------------
