I answered on the other question you asked. Double-check the formula you put here, as I think it needs a plus sign, in the parentheses. Also, use the other problem to guide you through this one. I hope you'll share your work, so we can help you through this one if you get stuck. :) 5/14/2014 | Regina G. Comment
