There are 3 living areas A, B, C with a total of 177 Covid 19 outbreaks. The number of patients from A, B, and Care 42, 60, and 75 respectively. 3 hospitals P, Q, R have prepared 50, 80, and 47 seats respectively for all the patients. (Assume each ambulance takes one patient) The costs (in RM) to deliver one patient from a living area to a hospital are summarized as follows A B C ? P 8.10 6.60 4.20 0 6.40 3.00 5.35 R 3.80 5.85 8.25 By using Northwest-Steppingstone method, determine the manner which the patients are to be transferred to the hospitals so that the total cost is minimum. Also determine such minimum cost.
