1) Refer to the graph above. The marginal physical product of thesixth worker is ------------- and the average product of sixworkers is -------------.
a)15;6
b)6;15
c)13;2

marginal physical product is the extra outputproduced by one more unit of an input (for instance, the differencein output when a firm's labor is increased from five to six units).Assuming that no other inputs to production change, the marginalproduct of a given input (X) can be expressedas:

MP =Y/X = (the changeof Y)/(the change of X).

1.)    b)6;15

Marginal Revenue Product is expressed as: MRP = Change in totalrevenue / Change in total labor

2.)    MRP= (74*2-60*2)=28 (B)

3.)    b)4 workers(REFER TO ABOVE)
