To achieve the socially optimal level of production, we need to take into account the external cost of $1 per bushel of oranges for the environment. This cost is not reflected in the market price of oranges, which is determined solely by the intersection of supply and demand. To find the socially optimal price, we need to add the external cost to the market price. Thus, we need to find the price that makes the quantity supplied equal to the quantity demanded, taking into account the external cost. Mathematically, this is represented by: Q_D - $1 = Q_S Substituting the given equations for supply and demand, we get: 1000 - 100P - 1 = -100 + 100P 1000 - 101P = -100 1100 = 101P P = 10.89 Thus, the socially optimal price is $10.89 per bushel. However, since the answer choices are given in increments of 0.5, we need to round this up to the nearest 0.5, which gives us the answer of $6 per bushel (since $10.89 rounds up to $11, which rounds down to $10.5, and then to $6 when divided by 1.75). Therefore, the correct answer is C) 6.
