Cullumber Ltd. purchased a delivery truck on January 1, 2018, at a cost of $74,160. The truck is expected to have a residual value of $7,910 at the end of its 4-year useful life. Cullumber has a December 31 year end. Use the diminishing-balance method and assume the depreciation rate is equal to double the straight-line rate.

Calculate the depreciation for each year of the truck’s life.

Well, well, well. Looks like we have a calculation conundrum on our hands! But fear not, for Clown Bot is here to add a touch of humor to the world of numbers and financial calculations. Let's dive in, shall we?

For the year 2018, we start with the cost of the truck - $74,160. However, since you mentioned using the diminishing-balance method with a depreciation rate double the straight-line rate, we need to calculate the double rate first. The straight-line rate is 1/4 (1 divided by the number of years, which in this case is 4). So, the double rate is 2 times 1/4, which gives us 1/2.

Now, let's calculate the depreciation for each year, using the diminishing-balance method and the double rate:

2018: $74,160 multiplied by 1/2 equals $37,080.
2019: We take the remaining balance from the previous year, which is $74,160 minus $37,080, giving us $37,080. Multiply this by 1/2 to get $18,540.
2020: The previous year's remaining balance is $37,080 minus $18,540, which equals $18,540. Multiply this by 1/2 to get $9,270.
2021: Finally, we take the remaining balance from the previous year, which is $18,540 minus $9,270, giving us $9,270. Multiply this by 1/2 to get $4,635.

So, according to my funny calculations, the depreciation for each year would be:
2018: $37,080
2019: $18,540
2020: $9,270
2021: $4,635

Remember, these calculations are based on the diminishing-balance method with a double depreciation rate. And if you're feeling puzzled, just remember that math can always use a little clowning around!

Using the diminishing-balance method with a depreciation rate of double the straight-line rate, the depreciation expense for each year can be calculated as follows:

2018:
Depreciation = (Carrying value at the beginning of the year) * (Depreciation rate)
Carrying value at the beginning of the year = $74,160 (purchase cost)
Depreciation rate = 2 * (1 / 4) = 0.5 (50% depreciation rate)

Depreciation in 2018 = $74,160 * 0.5 = $37,080

2019:
Carrying value at the beginning of the year = $74,160 - $37,080 (depreciation expense of the previous year)
Depreciation in 2019 = Carrying value at the beginning of the year * Depreciation rate

Depreciation in 2019 = ($74,160 - $37,080) * 0.5 = $18,540

2020:
Carrying value at the beginning of the year = $74,160 - $37,080 - $18,540 (depreciation expense of the previous years)
Depreciation in 2020 = Carrying value at the beginning of the year * Depreciation rate

Depreciation in 2020 = ($74,160 - $37,080 - $18,540) * 0.5 = $9,270

2021:
Carrying value at the beginning of the year = $74,160 - $37,080 - $18,540 - $9,270 (depreciation expense of the previous years)
Depreciation in 2021 = Carrying value at the beginning of the year * Depreciation rate

Depreciation in 2021 = ($74,160 - $37,080 - $18,540 - $9,270) * 0.5 = $4,635

Therefore, the depreciation for each year would be:

2018: $37,080
2019: $18,540
2020: $9,270
2021: $4,635

To calculate the annual depreciation using the diminishing-balance method, follow these steps:

Step 1: Determine the depreciable cost.
Depreciable Cost = Initial Cost - Residual Value
Depreciable Cost = $74,160 - $7,910
Depreciable Cost = $66,250

Step 2: Determine the depreciation rate.
The depreciation rate for the diminishing-balance method is twice the straight-line rate. Since the useful life is 4 years, divide 100% by 4 to get the straight-line rate.
Straight-Line Rate = 100% / 4 = 25%
Depreciation Rate = 2 * Straight-Line Rate
Depreciation Rate = 2 * 25% = 50%

Step 3: Calculate the annual depreciation.
In the first year, apply the depreciation rate to the depreciable cost.
2018 Depreciation = Depreciable Cost * Depreciation Rate
2018 Depreciation = $66,250 * 50%
2018 Depreciation = $33,125

In the subsequent years, apply the depreciation rate to the remaining book value (or net carrying amount) from the previous year.
2019 Depreciation = (Depreciable Cost - Accumulated Depreciation from 2018) * Depreciation Rate
2019 Depreciation = ($66,250 - $33,125) * 50%
2019 Depreciation = $33,125 * 50%
2019 Depreciation = $16,562.50

2020 Depreciation = ($66,250 - Accumulated Depreciation from 2018 and 2019) * Depreciation Rate
2020 Depreciation = ($66,250 - $33,125 - $16,562.50) * 50%
2020 Depreciation = $16,562.50 * 50%
2020 Depreciation = $8,281.25

2021 Depreciation = ($66,250 - Accumulated Depreciation from 2018, 2019, and 2020) * Depreciation Rate
2021 Depreciation = ($66,250 - $33,125 - $16,562.50 - $8,281.25) * 50%
2021 Depreciation = $8,281.25 * 50%
2021 Depreciation = $4,140.63

Therefore, the depreciation values for each year are as follows:

2018: $33,125
2019: $16,562.50
2020: $8,281.25
2021: $4,140.63
