The graphical solution procedure generally means you graph the constraint inequalities to identify the feasible solution region, then locate the objective function curve so as to maximize its value. When the objective function is a linear function, maximizing it generally means locating it at the vertex of the feasible region that makes it farthest from the origin.
The solution is
... (A, B) = (100, 50)
It would be logistics and inventory control because that is often done via computer and that job also controls the finances.
They issue recalls. A recall is when a company realizes that a product has a defect that might be dangerous or causes the product to malfunction. When a thing is recalled, all stores selling it send it back to the manufacturer, while people who bought it are allowed to return it for repair or often to get another product instead of that one for free.
