Answer:
correct option is E. four units
Step-by-step explanation:
given data
Units of Labor 0 1 2 3 4 5
Quantity of Output 0 10 18 25 31 33
Marginal Revenue 10 10 10 10 10 10
labor price unit = $60
to find out
how many labour firm should hire
solution
we can say firm should hire 4 unit labour
because as we know MRP is equal to wage so
and Marginal Revenue is constant so P = $10
so MPP of 4th labor will be
MPP 4th = 31 - 25
MPP 4th = 6
so MR Price = MPP × price
MRP = 6 × 10 = $60
so correct option is E. four units
