You can put this solution on YOUR website!
Cost of Company A at x day is 40x (because we multiply its rate of $40/day by the no. of days)
\n" ); document.write( "Cost of Company B at x day is 60 + 20x\r
\n" ); document.write( "\n" ); document.write( "40x = 60 + 20x
\n" ); document.write( "40x - 20x = 60
\n" ); document.write( "20x = 60
\n" ); document.write( "x = 3\r
\n" ); document.write( "\n" ); document.write( "Therefore, A & B cost the same in 3 days.
\n" ); document.write( "
\n" );
