Answer and Explanation:
a. The computation of operating profit is shown below:-
Profit per unit = Purchase price from outside per unit + variable cost of production internally
= $15 - $7
= $8
Total increment in operating profit = Profit per unit Ă— Total number of units
= $8 Ă— 24,000
= $192,000
b. Minimum transfer price = Variable cost = $7 (because polk has overcapacity and there is no change in fixed cost and polk minimum has to recover its variable production cost)
c. Maximum transfer price = purchase cost from outside supplier = $15 (because if the internal transfer piece is more than $15 Bishop will lose so he prefers to buy from outside and the company as a whole will lose $192,000 in incremental operating profit
