While doing battle with Krang in Dimension X, Raphael was exposed to a radioactive cloud. Three months later he notices that he has shrunk in height from 62 inches to 59 inches. After running some tests, Donatello determines that Raphael will continue to shrink at a rate that is proportional to his height. A. Find a formula formula for , Raphael's height in inches, months after being exposed to the radioactive cloud. Round the relative growth rate to four decimal places. B. How long will it take for Raphael to shrink to 30% of his original height? Round your answer to the nearest whole number.
