You have been hired by a charity based out of Toronto to recommend the best project they should pursue. They know that a project is successful if it impacts many people, is low cost to implement, and can be completed quickly. They don't know which of these factors are more important, but they think the number of people impacted is critical.

They are contemplating between the following projects:

1. Building 10 water wells in Sub-Saharan Africa - Each well costs about $5,000 to build and helps about 100 locals. Given the remote location and logistics in organizing local partners, the project will take about 3 years to complete.
2. Installing 1 water treatment plant on a Reserves - The plan will cost $50,000 to build and provides clean drinking water to about 700 people. It is expected to take about 9 months to complete the project.
3. Building and installing a greenhouse in northern British Columbia - The greenhouse will cost about $1M to build and provide fresh fruits and vegetables to about 5,000 locals at an affordable price. The project is of medium complexity and will take about 18 months to complete.
4. Providing non-perishable food items to local families - The charity can provide food hampers to 1,000 people, with each hamper costing about $100. This is an easy project to put together and will only take 2 months to complete.

You are to use the weighted factor model analysis to recommend a project for the charity to pursue.
