GreenFuel Ltd has outgrown its current site due to the demand for electric cars. A decision has already been made that the company wishes to expand in line with demand and has found two sites that would be suitable for their expansion plans, Site A and Site B. At the moment both sites would need a considerable investment to ensure they are able to provide all of the requirements for their customers.

The following table summarises the initial investment required, as well as the net cash inflows for years 1-5.
