C is produced using A and B as a raw material. To produce 1 kg C, 0.6 k A and 0.4 kg B are required. The selling price of C and the cost of the A and B are given in the following table.

C $/kg	A $/kg	B $/kg
0.25	0.07	0.06

The amount of the electricity to make the production is 1 kJ/kg C. The company have 4 generators to meet the electricity requirement. The cost and the daily capacities of the generators are given in the following table.

Generators	1	2	3	4
Cost ($/day)	70	50	120	140
Capacity kJ/day	300	600	500	1600

If the daily amount of produced C is limited with 2000 kg. Develop and solve the MILP model to determine which generators should be used and optimum daily production of C to maximize the profit. (The model should be represented in your answer sheet and also excel file)
