e number of flu cases in a certain town rose from approximately 100 one week to 220 in the next. Assume the number of cases is owing exponentially. Use this information to build an exponential model for the number of cases N (t), as a function of the time t in weeks. Assumet = 0 the week with 100 cases. Round A and b to 2 decimal places if =cessary. Use your model to find N(5). Interpret your answer for part b.
