Question

Java Help:

Scenario: North Carolina Medical Supply is researching purchasing Flint, a surgical robot. They have gathered data from several sources and need you to write a program to arrange this data in a report. They want to know what is the average rating for Flint, which users have given Flint above average ratings, and which companies rated Flint below average. They also want to know the cost per Flint, since they have noticed a difference in price based on the number of robots purchased.

Sample Data:

Name of Company                            # of Robots                 Cost (No tax included)                            Rating

Hospital A 15                                        $250, 000                            Below Average

Hospital B 30                                     $450, 000                               Above Average

Hospital C 3                                       $75, 000                                 Below Average

Hospital D 50                                      $500, 000                            Above Average

Answer 1

/*
* The java program that displays the name of the hospital, number of robots,
* cost of purchase and rating and also print the cost per flint on console
* output as a table format

Sample Output:

Name of Company # of Robots Cost(No tax included) Rating Cost/Flint
Hospital A 15 $250000 Below Average 16666.67
Hospital B 30 $4500000 Above Average 150000.00   
Hospital C 3 $75000 Below Average 25000.00
Hospital D 50 $500000 Below Average 10000.00
