During a snowstorm, Mei Mei tracked the amount of snow on the ground.
When the storm began, there were 4 inches of snow on the ground. For the
first 2 hours of the storm, snow fell at a constant rate of 2 inches per hour.
The storm then stopped for 7 hours and then started again at a constant rate
of 3 inches per hour for the next 5 hours. As soon as the storm stopped again,
the sun came out and melted the snow for the next 6 hours at a constant rate
of 3 inches per hour. Make a graph showing the inches of snow on the ground
over time using the data that Mei Mei collected.
