I had this problem and got it wrong on my quiz and have to know how to do it for my upcoming test and was looking for guidance to the answer

I calculated you should adjust Depreciation expense by 15,000.

I got to this answer first by calculating the book value of the asset being 65,000 in 2018 by using (120,000 - 10,000) / 10 years = 11,000 of depreciation per year x 5 years = 55,000. 120,000 - 55,000 = 65,000. I then calculated the Depreciation using the Double declining method from here using (2/5 years remaining) X 65,000 = 26,000. Depreciation expense would of been recorded at 11,000 under straight line and 26,000 under double decline making me adjust by 15,000.

Any help in pointing out where I went wrong would be appreciated

continu ng with the information presented in #1 above. ABC has ICO 0 $1.800.000 and corporate tax rate o 30%. Determine lco should be adjusted based on the ollow ng rmation: ABC purchased equipment for $120,000 on January 1, 2013 with an estimated 10 year useful life and $10,000 salvage value. ABC uses the straight-line method to depreciate this class of asset. At the end of 2018, ABC determined it was appropriate to change the depreciation method of this asset to the Double-Declining-Balance method. The bookkeeper was unaware of this change and already calculated 2018 ICO using the straight-line method Adjustment (if any) for Depreciation Expense (2018): $(Blank-4] ou determine at A C treated the transaction ? you need to increase co, enter your answer as a posit ve number: if you need o decrease C enter your answer as a negati e num er using 0 parenthesis correctly and that Ico does not need to be adjusted, enter NE for No Effect. You do not need to record your answer using 5 signs or commas
