Answer:
Net dollar advantage of buying from supplier $ 191.700
Step-by-step explanation:
Computations
Cost of internal production $ 27 per unit
Total units produced 29,000 units
Total cost of production $ 783,000
Cost of purchase $ 38 per unit
Incremental cost of production $ 9 per unit
Total incremental cost incurred in buying from outside -
29,000 * $ 9 $ 261,000
Add: Fixed costs retained (29,000 units * $ 9 *2/3) = $ 174,000
Total incremental costs $ 435,000
Rental Income $ 626,700
Net dollar advantage of buying from supplier $ 191.700
