The sprayer's base price is $820,000, and it would cost another $17,500 to install it. The machine falls into the MACRS 3-year class, and it would be sold after 3 years for $604,000. The MACRS rates for the first three years are 0.3333, 0.4445, and 0.1481. The machine would require an increase in net working capital (inventory) of $15,500.
