Formulating a Linear Problem

The steps for defining a linear problem include:

Identifying the decision variables.

Writing the objective function.

Mentioning the constraints.

Explicitly stating the non-negativity restriction.

A problem will be a linear problem if and only if the decision variables, objective function and constraints all are linear functions.

If all the three conditions are satisfied, then it is a linear problem.

Let $x1$ be the dollars invested in bonds, $x2$ be the dollars invested in home loans, $x3$ invested in auto loans and $x4$ be the dollars invested in personal loans.

Hence in this case, the linear problem is
$Max z = 10x1+ 16x2+ 13x3+ 20x4$

Subject to

$x1+ x$
