dq/dt = (0.2p + 3) dp/dt
so, at p=100,
dq/dt = 23 (-4) = -92
You will supply 92 fewer per week
The number of retro portable CD players you are prepared to supply to a retail outlet every week is given by the formula
q = 0.1p2 + 3p
where p is the price it offers you. The retail outlet is currently offering you $100 per CD player. If the price it offers decreases at a rate of $4 per week, how will this affect the number you supply?
