The following is a student solution to the inequality
5/12-(x-3)/6≤(x-2)/3
5/12-2/2*(x-3)/6≤4/4*(x-2)/3
5/12-(2x-6)/12≤(4x-8)/12
5-2x-6≤4x-8
-1-2x≤4x-8
-6x≤-9
x≥3/2

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.
