please solve with excel and picture all formulas and steps taken in excel.

4) The A&B Supermarkets have 3 warehouses A, B, and C, that ships supplies to their 3 stores. Their costs of shipping per unit are given below: 1 14 11 2 12 3 9 12 B 8 I I C 13 10 12 The capacities of A, B, and Care 240, 360, and 200 units, respectively, while the demands of stores 1, 2, and 3 are 400, 250, and 150, respectively. [Notice that the total supplies = total demands!) a) Formulate the transportation problem to minimize total cost for shipping. Please provide the actual shipping schedule derived from Solver. b) If the shipping routes can be changed so that the supplies can be transshippe from warehouse to warehouse, market to market, and even market to warehouse, would you recommend a new set of shipping routes given the following per unit cost shipping data: 1 1 B 1 2 3 A 0 1 5: 14 12 9 B 1 0 2 11 8 12 5 2 0 13 10 12 1 14 11 13 4 3 2 12 8 101 4 2 3 9 12 12) 3 c) What would be the new shipping routes and quantities? How are these different from those of a)? m NO
