As a manager, Mike uses linear programming (LP) to formulate a problem into a series of mathematical expressions. refers to the choices or alternatives Mike selects to minimize or maximize the value of his goals. a. Objective function
b. Decision variables
c. Optimization
d. Feasible region

Objective function is a function used in linear programming (LP) so as to maximize or minimize.

Linear programming are system of linear constraints used to optimize or solve a problem. The problem is being solved by selecting the variables that would be used to maximize or minimize the objective function from a list of several objective functions.

b. Decision variables

Step-by-step explanation:

The decision variable is the variable that decides that what would be the output. It presents the final solution.

Since in the given situation it is mentioned that the Mike uses linear programming for formulating a problem now the choices that chose for minimize or maximize the value would be the decision variables

Hence, the correct option is b.
