Answer:
A.$12,000
B.$8000
C.MRPL/PL = 3
MRPK/PK =2
D) Since each of the above calculated ratios are more than one, therefore adding additional worker or tractor will increase the total revenue for each of the dollar spent.
Step-by-step explanation:
(a) The Marginal Revenue Product of Labor (MRPL) can said to be the additional revenue generated when an additional worker is employed.
$66,000 - $54,000 = $12,000
Thus, MRPL is 12,000
b) Marginal revenue product of capital is
( 62000 - 54000)= $8000
c) MRPL/PL = 12000/ 4000= 3
MRPK/PK = 8000/4000=2
Therefore Since these two ratios are not equal it means the firm is not using the least cost combination of inputs.
d) Since each of the above calculated ratios are more than one, therefore adding additional worker or tractor will increase the total revenue for each of the dollar spent.
