Recall that profit can be computed in terms of revenue and cost. Assume that the annual widget sales match the annual widget demand and annual widget production. Construct a model for profit using the models for revenue and cost that you found in the Revenue and Cost sections. Give your model for profit P (x), where P (x) is the total annual profit in dollars for x widgets sold.
