Depreciation rate at the beginning of the year=30% Useful life rate at the beginning of the year equals ldots % square

To find the useful life rate at the beginning of the year, we need to understand the relationship between the depreciation rate and the useful life rate. The depreciation rate is the percentage of the asset's value that is depreciated each year, while the useful life rate is the total number of years over which the asset is expected to be used.Given that the depreciation rate at the beginning of the year is 30%, we can use the following formula to calculate the useful life rate:Useful life rate = 100 / Depreciation rateSubstituting the given depreciation rate into the formula, we have:Useful life rate = 100 / 30Simplifying the fraction, we get:Useful life rate = 100/30 = 10/3 ≈ 3.33Therefore, the useful life rate at the beginning of the year is approximately 3.33%.
