please help me answer this question

Consider the following mathematical model. Prepare a spreadsheet model for this model, and solve it using Excel solver to get an optimal solution. Max Z = 2* + *2 + 4x3 + 3x4 subject to *+x, +3x3 + 2x4 54 M-X3 +x, 21 *+2x2 +x3 +2x4 = 6 x120, x2 20, X, 20, x, 20 a. Use meaningful labels in your spreadsheet model. Labels include x1, x2, x3, and x4 for the name of the variables, constraint 1, 2, and 3 for the name of the functional constraints, right-hand side values, objective function coefficients, and objective function value. (5 marks) b. Copy each formula you have used in a cell of your spreadsheet model and paste it and its address here. For example, G8=SUMPRODUCT(C8:F8,C11:F11). (5 marks) c. Report a screenshot of your spreadsheet model that has been solved and the optimal solution can be seen in it. (15 marks)
