A few weeks into the deadly SARS (severe acute respiratory syndrome) epidemic in 2003, the number of cases was increasing by about 4% each day. On April 1, 2003, there were 1,804 cases. Find an exponential model that predicts the number of cases t days after April 1, 2003.f(t) =

Use it to estimate the number of cases on April 24, 2003. (Round your answer to the nearest integer. The actual reported number of cases was 4,439.) cases
