A medical researcher wants to determine the concentration C (in moles per liter) of a
tracer drug injected into a moving fluid with flow R (in liters per minute). Solve this
problem by considering a single-compartment dilution model (see figure). Assume that
the fluid is continuously mixed and that the volume V (in liters) of fluid in the
compartment is constant.
If the tracer is injected instantaneously at time , then the concentration of the fluid
in the compartment begins diluting according to the differential equation
when (a) Solve this differential equation to find the
concentration as a function of time. (b) Find the limit of as

A manufacturer charges $70 per unit for units that cost $60 to produce. To encourage
large orders from distributors, the manufacturer will reduce the price by $0.02 per unit
for each unit in excess of 100 units. (For example, an order of 101 units would have a
price of $69.98 per unit, and an order of 102 units would have a price of $69.96 per
unit.) This price reduction is discontinued when the price per unit drops to $64. Express
the price per unit as a function of the order size.
