A client is considering adding a new corporate bond, F, to their bond portfolio above. The zero coupon bond would be purchased for $810.52, matures in 8 years, and has a yield-to-maturity of 2.66%.

If the client added $50,000 worth of this bond to their bond portfolio, what would the new weighted average duration be of the new bond portfolio?
