Concept explainers
Sales The cumulative sales S (in thousands of units) of a new product after it has been on the market for t years are modeled by
During the first year, 8000 units were sold.
(a) Solve for k in the model.
(b) What is the saturation point for this product? (The saturation point is the limit of S as
(c) How many units will be sold after 5 years?
(d) Use a graphing utility to graph the sales function.
