James Company makes 1,000 units per year of a part it uses in the products it manufactures.

The unit product cost of this part is computed as follows:

Variable manufacturing cost $41 per unit

Direct fixed salaries $16 per unit

Allocated fixed costs $10 per unit

Unit product cost $67 per unit

From an outside supplier, James could buy all 1,000 units of the part for $60 per unit. If James buys the part from the supplier, the facilities now being used to make the part could be rented for $2,000.

Also, direct fixed salaries will decrease by 75%.

For all 1,000 units together, how much is the net dollar advantage (disadvantage) of purchasing the part rather than making it? (advantage or disadvantage? And how much?).
