please answering the part 2 "solving this LP problem using the graphical method", showing the steps, thank u

Jim operates a fish farm during the summer months in New Brunswick to supplement his income. He has questions about what he should feed his fish in order to minimize his costs. Currently, he's considering a combination of feed pellets available from local sources. Further to minimizing costs, Jim must also ensure that each fish receives an acceptable supply of calories and vitamins. He has formulated the following linear programming model: Let Xl be the number of pellets of feed type A in the diet Let X2 be the number of pellets of feed type B in the diet Min Z = $0.40 X1 + $0.80 X2 (Total Cost) Subject to: 80 X1 +100 X2 > 800 (Calories per day) 14 X1 + 7 X2 70 (Vitamins per day) X1 5 1/3 (X1 + X2) (Constraint 3) X1,x220 Spring/Summer 2019 ADM2302 X Business Analytics Assignment 1 Briefly explain or define each of these parts of the model: a) The 0.80 in the objective function b) The product of the 0.40 and X1 in the objective function (e.g. 0.40 X1) c) The 800 calories in the calories per day constraint d) The product of 100 and X2 in the calories per day constraint (e.g. 100 X2) c) The 7 units in the vitamins per day constraint f) The third constraint was added because the pellets of type A contain a chemical that can be toxic if ingested in large doses for fish. Explain what this constraint means in managerial terms. Solve this LP problem using the graphical method: g) Graph the constraints and identify the feasible region. h) Determine the optimal solution(s) and the minimum cost (show your calculations). Include a "managerial statement that communicates the results of the analyses (i.e., describe verbally the results). i) Determine the amount of slack for each of the constraints
