Your solution should clearly explain the closed contour you are using, and state clearly any
vanishing properties of integrals over contours that are being used. You are free to quote
from the lectures, the appropriate results on such vanishing properties, without deriving
these properties. Any residue calculations involved should be explained clearly.

- Steel Production Planning: Let S represent the amount of steel produced (in tons). Steel Production is related to the amount of labor used(L) and the amount of capital used ( C ) by the following function:S = 20L⁰˙³⁰C⁰˙⁷⁰In this formula L represents the units of Labor input and C the units of Capital input. Each unit of Labor costs $50, and each unit of Capital costs $100. a:Formulate an optimization problem that will determine how much labor and capital are needed to produce 50,000 tons of steel at minimum cost.
