Answer:
The advantage of this decision is $3 per unit.
Explanation:
The Net benefit is the tax saving on the transfer pricing.
First, we need to calculate the tax-saving rate
Tax saving rate = Tax on Subsidiary Y - Tax on Subsidiary X = 35% - 25% = 10%
Now calculate the excess discretionary transfer price
Excess discretionary transfer price = $80 - $50 = $30
Net benefit = Excess discretionary transfer price x Tax saving rate = $30 x 10% = $3 per unit
