Question
Given an annual capital investment of RM x million, along with the employment of y million
unskilled labour hours and z million skilled labour hours per year, the annual sugar production
output (in tonnes) of a sugarcane mill can be modelled by the function
16
Q(x, y, z) = -
-enz
100
in which the values of x, y, and z should adhere to the budget constraint of
2x² + y² + 2z² = 21
Apply both the D-test method AND the method of Lagrange multipliers to determine the
optimal allocation of capital investment and the most effective utilization of unskilled and
skilled labour force to maximize sugar production. Then, compare and comment on the two
methods used.
