A scuba diver studying marine life is 4 feet below sea level. From that depth, the diver descends 72.5 feet to the ocean floor. He then rises to 6.25 feet. He rests there. Where is the diver relative to sea level when he is resting? Create a number sentence and find the value where the diver is resting.

Create a question with this scenario you could ask that could be answered only by graphing or using logarithm. david estimated he had about 20 fish in his pond. a year later, there were about 1.5 times as many fish. the year after that, the number of fish increased by a factor of 1.5 again. the number of fish is modeled by f(x)=20(1.5)^x.
