Answer:
$22000 and $50000.
Explanation:
Given: Purchased value of equipment- $72000.
Residual value- $6000
Estimated useful life of equipment- $ 5 years.
Now, finding value of depreciation for 2011 using the sum of the years digits method.
Depreciation cost= [tex](\textrm{Purchased value - residual value}[/tex]
⇒ Depreciation cost= [tex](72000-6000)= \$ 66000[/tex]
∴ Depreciation cost= $66000.
Depreciation fraction for 1st year= [tex]\frac{5}{1+2+3+4+5} = \frac{5}{15}[/tex]
Depreciation expense for 1st year= [tex]\frac{5}{15} \times 66000= \$ 22000[/tex]
∴ Depreciation for 2011 is $22000.
Next, lets find out the book value at the end of first year.
Book value= [tex](\textrm{Purchased value - depreciation expense})[/tex]
Book value= [tex](72000 - 22000) = \$ 50000[/tex]
∴ Book value at December 2011 is $50000.
