Solve the problem.A company has 120 sales representatives, each to be assigned to one of four marketing teams. If the first team is to have three times as many members as the second team and the third team is to have twice as many members as the fourth team, how can the members be distributed among the teams? (Let x denote the number of members assigned to the first team, y the number assigned to the second team, z the number assigned to the third team, and w the number assigned to the fourth team. Let w be the parameter.)
A. x = 120 - 3w, y = 40 - w, z = 3w - 40, 0 ? w ? 40 B. x = 60 - 3w, y = 20 - w, z = 40 + 3w, 0 ? w ? 20 C. x = 90 - 9w/4, y = 30 - 3w/4, z = 2w, 0 ? w ? 40 D. x = 30 - 3w/4, y = 10 - w/4, z = 2w, 0 ? w ? 20
