Final answer:
The percent used up of Deere's depreciable assets in 2016 was 64.47%.
Step-by-step explanation:
To estimate the percent used up of Deere & Company's depreciable assets, we need to calculate the accumulated depreciation as a percentage of the total cost of assets. In 2016, the total cost of assets was $6,390 million, and the accumulated depreciation was $4,113 million. So, the percent used up of depreciable assets can be calculated as:
Percent used up = (Accumulated depreciation / Total cost of assets) x 100
= (4,113 / 6,390) x 100
= 64.47%
