Kylie and Ricardo decide to start a dog watching business for their neighborhood.  Kylie thinks it would be best to charge customers $27 for a membership and then $5 per time they walk a dog.  Ricardo thinks it would be best to charge $8 per dog walk.

Both plans will cost the same for 9 walks. How much money will 9 walks cost?
