9. LEARNING Ms. Klemperer told her English class that each week students tend to forget one- sixth of the vocabulary words they learned the previous week. Suppose a student learns $$60$$ words. The number of words remembered can be described by the function $$W ( x ) = 60 ( \frac { 5 } { 6 } ) ^ { x }$$ , where $$x$$ is the number of weeks that pass. How many words will the student remember after $$3$$ weeks?

$$34.72$$
