Manuel is also in Mr. Whittaker’s science class. He observed that the water level rose 1.8 millimeters per year, which matches the average annual trend. This occurred for 2.2 years. Explain how to determine the total variation in water level.
To determinethe total variation in water level you would multiply 1.8 by 2.2 (3.96) and I can check my answer by rounding 2.2 to 2 and 1.8 to 2 and multiply that which equals 4 and 4 is close to 3.96
