Think of this first practice problem as a warm up. We have found over the years that many students make mistakes on the simple concepts (converting to common units, translating times from months to years, etc.). So, let's make sure we are all comfortable with these basic ideas before moving on to the more complicated concepts. So, for this problem it is all about the basics, with no trouble (I hope).
