The president of a consulting firm wants to minimize the total number of hours it will take to complete four projects for a new client. Accordingly, she has estimated the time it should take for each of her top consultants-Charlie, Betty, Johnny, and Rick-to complete any of the four projects, as follows: Consultant Charlie Betty A 13 11 15 17 Project (Hours) B C 16 11 15 14 22 12 17 12 D 13 18 15 22 Johnny Rick Assume there must be one-to-one matching between consultants and projects. After the row and column reductions, what is the resulting entry in the new table for assigning Rick to project D? 0 hours 8 hours O 10 hours O 9 hours O 22 hours
