Suppose the number of points on an economics midterm (P) can be characterized by the following production function:
P = 10H-4B
where H is the number of hours spend studying and B is the number of beers in the week prior to the midterm.
(a) What is the marginal product of H and B? Does the law of diminishing returns apply to H or B?
(b) What shape will the isoquants have for this production function?
(c) Does this production function exhibit increasing, constant, or decreasing returns to scale?
