The price of a popular gaming console is related to the quantity demanded by the equation 2p² + x² = 41 where p is the price (in hundreds of dollars) and x is the number of consoles demanded (in thousands). Determine how fast the quantity demanded is changing when the price is set at $400 (p = 4), the quantity demanded is 3000 (x = 3), and the price is decreasing at the rate of $2 per week (p' = -0.02). Give your answer as a whole number (remember that the quantity demanded is measured in thousands). Make sure to indicate whether it is increasing or decreasing and include the correct units.
