Margo, a calendar year taxpayer, paid $1,580,000 for new machinery (seven-year recovery property) placed in service on August 1, 2023. Use Table 7-2. Required: a. Assuming that the machinery was the only tangible property placed in service during the year, compute Margo's maximum cost recovery deduction. Note that for 2023 the maximum Section 179 deduction was $1,160,000. b. How would your computation change if Margo paid $3,100,000 for the machinery? Note that for 2023 the Section 179 deduction threshold amount was $2,890,000. c. How would your computation change if Margo paid $4,750,000 for the machinery? d. How would your answer to part (a) change if the machinery was purchased in 2022 instead of 2023 ? Note: For all requirements, round your intermediate computations to the nearest whole dollar amount. Answer is complete but not entirely correct
