Given the total cost as C, price of labour (L) as PL, price of capital (K) as PK, an isocost curve..

Given the whole require as C, charge of labour (L) as PL, charge of principal (K) as PK, an isorequire flexion can be drawn from which of the subjoined operations?

(a) K = C/PK + (C/PL)L

(b) C = C/PL + C/PK

(c) C = K ⋅ PK + L ⋅ PL

(d) L = C/PK − (C/PL)K

Expansion course is a unswerving row when the formation operation is

(a) homogeneous,

(b) non-homogeneous

(c) of any form
