Question

I am needing to know what constraints to put into the solver part

Planting Costs Amounts Planted Amounts Spent (per acre) X1 (corn) $               20.00 $                        -   X2 (soybeans) $               15.00 $                        -   X3 (wheat) $               12.00 $                        -   Total 0 $                        -   Part B Define: Corn = X1, Soybeans B = X2, Wheat = X3 Minimize: z= 20X1 + 15X2 + 12X3 Constraints: #1--X1 + X2 + X3 >= 500 acres #2--X1 + X2 + X3 <= 600 acres #3--X1 - 2X3 = 0 0 0 0 #4--X1 - X2 - X3 >= 0 0 #5--X2 <= 200 #6--X1, X2, X3 >= 0

Explanation / Answer

Constraint to put in the solver part:-

total number of plants hould be between 500 and 600

X1 + X2 + X3 >= 500

X1 + X2 + X3 <= 600

wheat plants should be twice the number of corn plants

X1 - 2X3 = 0

Total number of corn plants should be greater than both wheat and soyabean plans combined

X1 - X2 - X3

Number of soyabean plants should be less than 200

X2 <= 200
