Answer:
the book value is $39,000
Step-by-step explanation:
The computation of the book value is shown below;
First the depletion cost per unit is
= $285,000 ÷ $950,000
= 0.30
Now the depletion expense is
= 0.30 × 820,000
= $246,000
Now the book value is
= $285,000 - $246,000
= $39,000
Hence the book value is $39,000
