Step-by-step explanation:
For Mar.20 transaction, the replace of the transmission make the delivery truck "newer". In other words, the old transmission system of the truck had been depreciated and reflecting through the Accumulated Depreciation account which should be removed to raise up the Net book value of the Delivery truck to truly reflect the rise in value of the Truck given its newly transmission system.
For June.11 transaction, the new installation of hydraulic lift obviously improve the value of the truck which should be capitalized to update the truck's value in accounting book.
For Nov.30, it is a normal repairs/maintenance activities which do not have significant influence on the truck value. So, it should be expensed.
