Solve the following model using linear programming and determine
the values of the decision variables and objective function. Then,
round the decision variables values down to the nearest integer and
determine the value of the decision variables and objective
function, this is an approximate answer to solving the model using
integer programming. Observe if the rounding provides a "feasible"
solution, all constraints are satisfied. Finally, solve the model
using integer programming and determine the values of the decision
variables and...
