Project A: Expand the manufacturing facility to increase capacity by 20 percent. This investment is expected to cost $360,000 and generate net cash flow of $80,000 per year for the next eight years.

Project B: Overhaul the company website to optimize the user experience and generate more traffic from online advertising. This project would cost $200,000 and is expected to generate an additional $100,000 in sales for the next 10 years. Assume that the contribution margin is 42 percent and that there would be no increase in fixed costs, including depreciation.

Project C: Invest in solar panels and more fuel-efficient delivery vehicles to reduce operating expenses (e.g., electricity and fuel) and the companys carbon footprint. The initial investment in assets would be $360,000, which would be depreciated over five years. The investment is expected to increase net income by $18,000 per year, after the depreciation adjustment.
