An apparel company is considering replacing the existing machine that produce their flagship suits. They will pick one of two machines: A and B.

At the end of year 7, Machine A will be sold for $9,000 (salvage value at t = 7). Machine B costs $40,000 to install, $5,000 to operate per year for 8 years. At the end of year 8, Machine B will be sold for $10,000 (salvage value at t = 8). The companys cost of capital is 5%. Determine which machine the company should choose and explain why.
