4. You may use computer for this. You do not need to attach the code in the file you upload to Gradescope, but show the final matrices you used/got from using computer e.g. if you used computer to find the inverse matrix, write down what A-1 on paper. Consider the same consumption matrix as problem 1. (a) How much will production change for each industry if the demand of electricity increases by 5 units? (b) Suppose the open sector demand for fishery, electricity, crops and livestock is 100, 200, 300, and 400 units, respectively. Determine the total production needed to satisfy all demands. (c) If the open sector demand for fishery, electricity, crops, and livestock is 300, 200, 350, and 250 units, respectively, how many units of each are used internally? Determine which industry used the highest percentage of their total production internally. F E L F E CL 0.15 0.1 0.05 0.05 0 0.2 0.2 0.1 0.4 0.01 0.02 0.1 0.1 0.25 0.3 0.25 4.
