Explanation of Solution
Given data:
The farmer Jane owns 45 acres of land and planning to plant with wheat or corn.
On planting wheat, she yields $200 profit and corn yields $300 profit.
Given table:
Wheat | Corn | |
Labor | 3 workers | 2 workers |
Fertilizer | 2 tons | 4 tons |
Consider
Objective function:
Considering the constraints,
Constraint 1: Total acres of land used
Constraint 2: Maximum number of workers to be used is 100
Constraint 3: Maximum tons of fertilizers are 120 tons.
Expressing the constraint 1 in terms of
Expressing the constraint 2 in terms of
Expressing the constraint 3 in terms of
Therefore, the mathematical model of given LP is,
Subject to the constraints,
Converting the inequality constraint without adding any variable:
