2.         In 2011, Liberty Travel received more requests for travel brochures to Hawaii than to Las Vegas. Therefore, in 2012, Liberty Travel sold more travel packages to Hawaii than to Las Vegas.

4.         Healthy Snacks cookies are fat free. So eat as many as you like and you will not gain weight.

Solution

2. As it is given that Liberty Travel recieved more requests for travel brochers to Hawaii than to Las Vegas. Which implies that in 2011 more people were looking for different distinations in Hawaii than in Las vegas. Now in 2012 people might now look for Las vegas as well so we can not relay on the previous year preferences of the people, as it might happen that more people look to go to Las vegas.

4. Since gaining weight does not depend only on eating fat free things, as if we do not do excersis on daily basis we would end up gaining weight. So only eating Healthy Snacks cookies does not imply that we will not gain weight.
