Betty is comparing the cost of a fresh lobster dinner at two different restaurants. The first restaurant
charges $25 for the meal, plus $3 per kilogram for the lobster she picks. At the second restaurant,
Betty would pay $2 per kilogram for the lobster, in addition to $30 for the meal Betty realizes that, in
theory, dinner at both restaurants could cost the same amount if the lobster had a certain weight.
