Question:

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?
