Not relevant to this class or real life. Where on the graph will you find how deep the snowpack is on May 20th? How long will it take for the snow to melt completely? Where can you find this information on the graph? How much snow melts every day? Where can you find this information on the graph? Can you find it in your formula? How big was the snow pack on May 5th? Where can you find this information on the graph? Can you predict what the snow pack was on January 1st?
