Answer: $12,000
Explanation:
Tebit should offer the amount that Naploc has spent so far on the equipment as the minimum price. Naploc has yet to start production and so has not incurred any sort of variable costs which may degrade or add to the value of the equipment.
The only cost to Naploc so far therefore as a result of the equipment is the $12,000 that has been spent on it already and this is the only relevant amount at that moment therefore it is the minimum that should be offered to entice Naploc to part with it.
