A firm manufactures a commodity at two different factories, Factory X and Factory Y. The total 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) = 1x^2 + xy + 8y^2 + 200
A) If the company's objective is to produce 1,200 units per month while minimizing the total monthly cost of production, how many units should be produced at each factory? (Round your answer to the nearest 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.)
