Both funds have 1,000 shares outstanding. a. What is the NAV of each fund using these prices? (Round your answers to 3 decimal places. (e.g., 32.161)) b. If the price of ATT stock increases to $56.25 and the price of Toro stock declines to $92.292, how does that impact the NAV of both funds? (Negative amounts should be indicated by a minus sign.
