According to a report, the number of centenarians (people older than 100) in a certain population is doubling about every 10 years. In 2015, there were approximately 5,037 centenarians in that population. (a) If this trend continues, find an equation for a model that would predict the number of centenarians in the population t years after 2015. C(t) = (b) Use your model to estimate the number of centenarians in the population in 2050. (Round your answer to the nearest whole number.) centenarians
