Answer:
Option B is correct
The maximum price to be paid is = $64000
Explanation:
To determine the the maximum price we would compute using the relevant costs of internal production.
The maximum price to be paid to external supplier should be the total relevant costs associated with internal production.
Total relevant cost of internal production = 34,000 + 15,000 +9000 + 6000
The maximum price to be paid is = $64000
Note that the fixed overhead of $6000 is associated with the internal production the balance of 4,000 is irrelevant and would be incurred either way.
