how is it A??

Read the following case and answer the four questions that follow: A professor has been contacted by five not-for-profit agencies that are willing to work with student consulting teams. The agencies need help with such things as budgeting, information systems, coordinating volunteers, forecasting and distribution. Although each of the four student teams could work with any of the agencies, the professor feels that there is a difference in the amount of time it would take each group to solve each problem. The professor's estimate of the time, in days, is given in the table below. Team A B Budgeting 32 34 30 40 50 Projects Information Volunteers Forecasting Distribution 28 37 36 38 32 35 44 42 25 38 32 35 30 42 28 26 38 40 34 c D E Let Xi denote if team i (A=1.B=2.C=3.D=4, E=5) is assigned to projectj (Budgeting =1. Information=2, Volunteers =3, Forecasting = 4, Distribution=5) 29. If a team can be assigned to more than one project, then, in the optimal assignment, which team(s) would DEFINITELY NOT be used? a. A. b. B c. C d. D e. E
