please help solving the following question

The Conde Nast Traveler Gold List for 2012 provided ratings for the top 20 small cruise ships (Conde Nast Traveler website, March 1, 2012). The data shown below are the scores each ship received based upon the results from Conde Nast Traveler's annual Readers' Choice Survey. Each score represents the percentage of respondents who rated a ship as excellent or very good on several criteria, including Shore Excursions and Food/Dining. An overall score was also reported and used to rank the ships. The highest ranked ship, the Seabourn Odyssey, has an overall score of 94.4, the highest component of which is 97.8 for Food/Dining.

thank you
