Question 7: On January 1, 20X1, a utility building was purchased for $2,190,000. Assuming a 25-year useful life and its worth to be $246,000 at the end of its life, how much would the "depreciation expense be in 20X2" using a 150%-declining balance method? Use the DDB formula. Question 8: Assume the same details as Question 7, except that the utility building was purchased on September 1, 20X1. Use the DDB formula. Hint: This is a bit challenging, so look carefully at both my DDB formula examples shown earlier and take pieces from each to create the necessary formula for this specific question.
