Section 2.2 (81) In the early stages of the deadly SARS (severe acute respiratory syndrome) epidemic in 2003, the number of cases was increasing by about 18% each day. On March 17, 2003 (the first day for which statistics were reported by the World Health Organization), there were 167 cases. Find an exponential model that predicts the number of cases "t" days after March 17, 2003, and use it to estimate the number of cases on March 31, 2003. (The actual reported number of cases was .)
