NOTICE - I did make an error when adding - the final answer should have been 7.3689 not 7.6689 - however - on quizzes and tests - take advantage of the answer choices! Even with my error - if I had had four answer choices listed the correct answer of 7.3689 most likely would have been the closest answer to what I got. We usually can make small adding or subtracting errors and still choose the correct answer!
