\n" ); document.write( "An airline that flies from LA to Albuquerque with a stopover in Phoenix charges a fare of $45 to Pheonix and a fare of $60 from LA to Albuq. A total of 185 passengers boarded the plane in LA and fares totaled $10,500. How many passengers got off of the plane in Pheonix?\r

You can put this solution on YOUR website!
you didn't multiply the WHOLE equation by -45 (what about the 185?) \n" ); document.write( "
