A lake’s level dropped 3 3/4 inches for 21 days during a drought. A heavy rainstorm raised the level by 8.25 feet. Afterwards the level dropped 9.5 inches per day for 4 days. Scientists want to determine if the water level increased. Use your knowledge of rational numbers to determine the change in water level. 1) Complete the S and O steps - S – O – 2) Draw a model to represent the problem in the space provided 3) Determine the level of the lake’s water after all the events.
