There are 30 fish in a tank. the fish are either orange or red. there are 12 more orange fish than the number of red fish, how many fish are orange? how many fish are red?

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.
