cost (in dollars) of manufacturing depends on the quantities, `x and y produced at each
factory, respectively, and is expressed by the joint cost function:
*C(x,y)=4 x^2 + xy + 8 y^2 + 3600
A) If the company's objective is to produce 800 units per month while minimizing the total

answer to whole units, i.e. no decimal places.)
To minimize costs, the company should produce:
at Factory X and
at Factory Y
B) For this combination of units, their minimal costs will be
dollars. (Do not enter any commas in your answer.)
