Run the program with 3 grades per student using the sample data below. Mary Brown 100 90 90 George Smith 90 30 50 Dale Barnes 80 78 82 Sally Dolittle 70 65 80 Conrad Bailer 60 58 71 You should get the following results: Mary Brown has an average of 93.33 which gives the letter grade of A George Smith has an average of 56.67 which gives the letter grade of F Dale Barnes has an average of 80.00 which gives the letter grade of B Sally Dolittle has an average of 71.67 which gives the letter grade of C Conrad Bailer has an average of 63.00 which gives the letter grade of D
