Browning Montana holds the US record for the greatest temperature drop in one day. On January 23, 1916, the temperature changed by an average of -4.17 degrees per hour. To the nearest degree, what was the total temperature change after 24 hours???

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.
