The rational expression 130 x 100 − x describes the cost, in millions of dollars, to inoculate x percent of the population against a particular strain of flu. a. Evaluate the expression for x = 40 , x = 80 , and x = 90 .Describe the meaning of each evaluation in terms of percentage inoculated and cost. b. For what value of x is the expression undefined? c. What happens to the cost as x approaches 100%? How can you interpret this observation?
