how to round this because i am confused: 132 how did we get 11.5 isn't it supposed to be only 11 because 2 is less than 3 so 11 how did we get the .5

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.
