Avellaneda-Stoikov Reservation Shift

Using the Avellaneda-Stoikov reservation price r = mid - q*gamma*sigma^2, the mid is 80.00, you are long q = 25 lots, risk aversion gamma = 0.10, and per-step volatility sigma = 0.40 (so sigma^2 = 0.16). How far below the mid is your reservation price, and what is r?
