This is game theory and please show all work/explain. I submitted the question as a picture.

4. A firm produces two products, X and Y. The production technology displays the following costs, where C(i,j) represents the cost of producing i units of X and j units of Y: C(0,50) = 100 C(5,0) = 150 C(0, 100) = 210 C(10,0) = 320 C(5,50) = 240 C(10,100) = 500 Does this production technology display economies of scale? of scope
