 the software itself gives a solution; please look that over and tell us where you got stuck. if you don't have access to the software, one student posted the problem in a different thread. you'll notice also that there is a typo and the correct answer should be multiplied by R.. _________________Tim SandersManhattan GMAT Instructor
