The Institute finds that the average student taking Elementary Shorthand will progress at a rate given by
dQ/dt=k(80Q)
in a 20 wk course, where Q(t) measures the number of words of dictation a student can take per minute after t wk in the course.
If the average student can take 60 words of dictation per minute after 5 wk in the course, how many words per minute can the average student take after completing the course?
Round the answer to the nearest word.

Assume a solution Q=Ce^rt + K
