In short run, workers are variable inputs. and ovens are also variable inputs.

A variable input is a factor of production which can be changed in the short run, that is, varied. On the other hand, factors of production which remain fixed in the short run are called fixed inputs. Although all inputs are variable in the long run.

The Marginal product of labor (MPL) is the change in output that results from employing an added unit of labor.

Formula for marginal product= change in total product or output / change in labor units.

Production function shows functional relation between physical output and input. It is derived by plotting output levels corresponding at each labor unit.

Rosa's total cost=fixed cost ($15) + variable cost ($30 per worker)

Thus total cost is calculated at each level in the table and plotted graphically against output levels.
