    Among all deaths from a particular disease, the percentage that is smoking related (21–39 cigarettes per day) is a function of the disease’s incidence ratio. The incidence ratio describes the number of times more likely smokers are than nonsmokers to die from the disease. The following table shows the incidence ratios for heart disease and lung cancer for two age groups. For example, the incidence ratio of 9 in the given table means that smokers between the ages of 65 and 74 are 9 times more likely than nonsmokers in the same age group to die from lung cancer. The rational function P(x) = 100(x - 1)/x, models the percentage of smoking-related deaths among all deaths from a disease, P(x), in terms of the disease’s incidence ratio, x. The graph of the rational function is shown. Use this function to solve, What is the horizontal asymptote of the graph? Describe what this means about the percentage of deaths caused by smoking with increasing incidence ratios.
