Chapter 6.5, Problem 36E
Mixture In Exercises 35-38, consider a tank that at time
A 200-gallon tank is full of a solution containing 25 pounds of concentrate. Starting at time t - 0, distilled water is admitted to the tank at a rate of 10 gallons per minute, and the well-stirred solution is withdrawn at the same rate.
(a) Find the amount of concentrate Q (in pounds) in the solution as a function of r,
(b) Find the time at which the amount of concentrate in the lank reaches 15 pounds.
(c) Find the amount of concentrate (in pounds) in the solution as r -> oo.

Decide whether the problem can be solved using precalculus, or whether calculus is required. If the problem can be solved using precalculus, solve it. If the problem seems to require calculus, use a graphical or numerical approach to
estimate the solution.
STEP 1: Consider the figure in part (a). Since this region is simply a triangle, you may use precalculus methods to solve this part of the problem. First determine the height of the triangle and the length of the triangle's base.
