In Exercises 43 through 46, p = D(q) is the demand curve for a particular commodity; that is, q units of the commodity will be demanded when the price is p = D(q) dollars per unit. In each case, for the given level of production q₀, find p₀ = D(q₀) and compute the corresponding consumers’ surplus.

D(q) = 4(36 − q²); q₀ = 2 units
