Aforest fire covers twice the amount of forest as it did 3 days ago. if the fire covered 300 square miles 3 days ago and it continues to grow at the same rate, how many square miles will it cover 12 days from now?

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. create a question you could ask that could be answered only by graphing or using a logarithm.
