Suppose the wholesale price of a certain brand of medium-sized eggs p (in dollars/carton) is related to the weekly supply x (in thousands of cartons) by the equation .



If 25,000 cartons of eggs are available at the beginning of a certain week and the supply is falling at the rate of 1,000 cartons/week, at what rate is the wholesale price changing? (Hint: To find the value of p when , solve the supply equation for p when ).





A. Increasing at the rate of 3.6 dollars/carton/wk

B. Increasing at the rate of 3.7 dollars/carton/wk

C. Dropping at the rate of 3.7 dollars/carton/wk

D. Dropping at the rate of 3.7 dollars/carton/wk

E. Dropping at the rate of 3.6 dollars/carton/wk
