Question
To create a saline solution, salt water with a concentration of 40 g/L is added at a rate of 500 L/min to a tank of water that initially contained 8000 L of pure water. The resulting concentration of the solution in the tank can be modelled by the function C(t)= 40t/160+t ,where C is the concentration, in grams per liter, and t is the time, in minutes.
a) What restrictions must be placed on the domain of C if the tank has a maximum capacity of 150 000 L?
b) Complete the table of reasonable values in the context of the problem.
c) Graph the function in the context of the problem. Clearly label axes, asymptote, and intercept(s) in the ruler-paper-pencil style.
