No excel please. Thank you.

Carlos Bakery is looking to purchase a new oven. Capital and installation costs are $630,000. Carlos himself wishes to depreciate this expense in a straight-line fashion over 4 years but you suggest that using a 4-year MACRS schedule (33.33% in year 1, 44.45% in year 2, 14.81% in year 3, and 7.41% in year 4). If the bakery's marginal tax rate is 30%, what is the NPV of choosing the MACRS schedule over a straight-line schedule if the discount rate is 6%? $3,729 $6,444 $4,475 $7,732 $5,370
