16. A. Price-Demand The market research department of a supermarket chain has de-
termined that, for one store, the marginal price p'(x) at x tubes per week for a
certain brand of toothpaste is given by
p'(x) = -0.015e 0.01x
Find the price-demand equation if the weekly demand is 50 tubes when the price
of a tube is $4.35. Find the weekly demand when the price of a tube is $3.89.
