(a) (b) State the optimal delivery plan and cost. Contactgear must change couriers for the Selangor - San delivery (refer c13) but they do not want to recalculate their delivery plan from scratch as this would incur extra costs. By performing Sensitivity Analysis, identify the range of optimality for c13 for which the current basis remains optimal.
