Tom always keeps his 4 gardens clean. he takes 20 minutes to clean a single garden. how much time will it take to clean all 4 gardens?

15 and 14.7 are 1 apart, so 15 – 14.7 must be 1.

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.
