b. $31,282.
c. $37,583.
d. $56,700.

a. $33,859

Explanation:

The computation of the depreciation expense for the year 2022 is given below;

The Depreciable Value of the Asset is

= Cost - Residual Value

= $212,000 - $21,000

= $191,000

Now  

Total Sum of the Years  is

= (1+2+3+4+5+6+7+8+9+10)

= 55

Now

Depreciation for the year 2022

For Jan 1st 2022 to Sept 30 is

= 10 ÷ 55 × 9 ÷ 12  × $191,000

= $26,045

And,  

For Oct 1st Dec 31 is

= 9 ÷ 55 × 3 ÷ 12 × $191,000

= $7,813

So,  

Depreciation expense is

= $26,045 + $7,814

= $33,859
