A farmer plans to mix two types of food to make a mix of low cost feed for the animals in his farm. A bag of food A costs $10 and contains 40 units of proteins, 20 units of minerals and 10 units of vitamins. A bag of food B costs $12 and contains 30 units of proteins, 20 units of minerals and 30 units of vitamins. How many bags of food A and B should the consumed by the animals each day in order to meet the minimum daily requirements of 150 units of proteins, 90 units of minerals and 60 units of vitamins at a minimum cost? Just formulate this problem in the linear programming model with equations for objective function and constraints. hint: Refer to the solved minimization problem (fertilizers) in class and the assignment)

Solutions

Expert Solution

Objective function refers to the function that is either maximized or minimized. The constraints may be equalities or inequalities. So, in linear programming problems, linear objective functions are minimized or maximized which is subject to linear constraints. Thus, in a linear programming problem the objective function and the constraints must be linear functions of the decision variables.

Say there are two types of workers, low productivity types (60% of the population) and high productivity types (40% of the population). They have lifetime productivity of 200 and 400 respectively. The employer knows the proportion of each type and their relative productivity but cannot distinguish between individuals’ future productivity at the point of hiring. What wage would a competitive employer pay? [10] Say the cost of education for a low productivity worker is 30. A high productivity worker enjoys...
