Final Answer:
As of December 31, 2015, the net amount, including accumulated depreciation, for Garden Company's machine should be $2,207,407.
Step-by-step explanation:
To calculate the accumulated depreciation using the sum-of-the-years'-digits method, we need to follow a specific formula. The formula for sum-of-the-years'-digits depreciation is:
Depreciation Expense =
![((n - x + 1))/((n \cdot (n + 1))/(2)) * \text{Cost} \]](https://img.qammunity.org/2024/formulas/business/high-school/490hk0tsqjatecx8qnb74s1ymvvsnufzql.png)
where n is the useful life of the asset in years, x is the current year, and Cost is the original cost of the asset.
For Garden Company's machine in 2015, with a useful life of 9 years and it being the second year (2015 - 2014 + 1), the formula becomes:
Depreciation Expense 2015 =
![((9 - 2 + 1))/((9 \cdot (9 + 1))/(2)) * \$2,800,000 \]](https://img.qammunity.org/2024/formulas/business/high-school/f2hch86p5i9sncg0a3d7lfygch1okbly03.png)
Solving this gives the depreciation expense for 2015. To find the accumulated depreciation, we sum the depreciation expenses for each year up to 2015.
Accumulated Depreciation 2015=
![\text{Depreciation Expense}_(2014) + \text{Depreciation Expense}_(2015) \]](https://img.qammunity.org/2024/formulas/business/high-school/pzkt5ho5hrws9tkymj01yvf2wrnsrf1shd.png)
Finally, subtracting the accumulated depreciation from the original cost gives us the net amount for the balance sheet:
Net Amount 2015 = Cost - Accumulated Depreciation(2015)
Plugging in the numbers, we find the net amount to be $2,207,407.
