Without the tip, she paid:
\n" ); document.write( " $\"+15+-+2.2+=+12.8+\"$
\n" ); document.write( "Let $\"+x+\"$ = number of miles for cab ride
\n" ); document.write( " $\"+1.6+%2B+.8x+=+12.8+\"$
\n" ); document.write( " $\"+.8x+=+11.2+\"$
\n" ); document.write( " $\"+x+=+14+\"$
\n" ); document.write( "The cab ride was 14 mi \n" ); document.write( "

\n" );
