Suppose that the number of Bob’s Bits computers that can be sold when its price is P (in dollars) is given by a linear function N(P), where N(1000) = 10,000 and N(1500) = 7500.
(a) Determine N(P).
(b) What is the slope of the graph of N(P), including units? Describe what the slope represents.
(c) What is the change ΔN in the number of computers sold if the price is increased by ΔP = $100?
