Answer:
if the firm processes A and B into X and Y, it will lose $25
Step-by-step explanation:
total costs of producing product A and B = $90 (common input) + $36 (processing) = $126
selling price of A and B = $53 + $113 = $166
profit of selling A and B = $166 - $126 = $40
if A and B are processed further, the cost of X and Y = $126 + $33 + $66 = $225
selling price of X and Y = $80 + $160 = $240
profit of selling X and Y = $240 - $225 = $15
if the firm processes A and B into X and Y, it will lose $40 - $15 = $25
