** Students give 1 water dollar for each trip to the drinking fountain. Five water dollars are required for 5 liters of water used, 20 water dollars are required for 20 liters of water used, etc. Saving 5 liters of water saves five water dollars, saving 35 liters saves 35 water dollars, etc. Savings are given back to the students as refunds.
