"Cee-ing Eye Corp. needs to decide whether to invest in research on a new drug that would instantly and painlessly cure most eyesight problems. Investing in research on the drug is estimated to cost $9 million to be paid immediately. If it decides to invest in research, the probability of technical success is 0.48. If Cee-ing Eye Corp. has technical success, it can choose between a basic or aggressive marketing strategy. A basic marketing strategy will cost the firm $4 million, and an aggressive marketing strategy will cost $10 million. The cost of the marketing strategy will be incurred in year 3. An aggressive marketing strategy has a 0.93 probability of success, and a basic marketing strategy has a 0.65 probability of success. The net cash flow given marketing and technical success will be $97 million in year 4. The net cash flow with no marketing success but with technical success will be $18 million in year 4. If there is no technical success, there is no other cash flow expect for the immediate cost of investing in research. If Cee-ing Eye decides not to invest in research, its net present worth (NPW) equals $0. You should assume the cash flow is $0 in each year except for years 0, 3, and 4. Cee-ing Eye Corp. will choose the alternative with the largest expected NPW, and its MARR is 18%. What is the expected NPW of the optimal alternative? Express your answer in MILLIONS of dollars. In other words, if the correct answer is $12.3 million, enter 12.3."
