By setting up a well-documented spreadsheet solve the following abstract linear programming problem. Make sure that you use the Linear Solver (Tools / Solver / Options / Solver Engine / Lincar Solver). Maximize the objective expression: 44r, + 54r2 + 492a+ 44r4 +50rs under the constraints: +10r1 + 10r2 +9r3+11r4+11rs < 1202 +10r1 + 11r2 +9rg +7x4 +7rs < 957 +8r + 7x2+ 10r3+6r4 + 11rs 979 +81 + 13r2 + 10rs + 12r4 +1lrs < 1279 +821 + 13r2 + 11r3 + 8r4+ 10rs < 1132 1, 2, 73, 4, Is 2 0 Write down the values of the variables that maximize the objective expression, along with the maximum value of the objective expression and submit these values in pdf format, following the instructions on clickUP. Save your spreadsheet with filename "SupExLinProg" and submit the spreadsheet by following the instructions on clickUP.
