Final Practice Exam and its
Solutions.

Practice Exam 3 and its
Solutions.
NOTE: The solutions are not numbered the same way (they are in the same order). The solution to 3f is in the last page.

Homework 12 is due on Friday May 30, 2014:
Section 11.8: 1, 5, 11, 12, 15, 17.

There's no class on Monday because it is Memorial Day

Practice Exam 2 and its
Solutions.
NOTE: The solutions are not numbered the same way (they are in the same order). The solutions to 8 are not included since the table of those solutions is on the compound interest lecture notes.

On the following link you can find the actual graphs of the examples we did in class. You can see they have the same shape.

The word problem worksheet is here, and its solutions are here. Note that the answer for part d in exercise 1 should be 2010 instead of 2011 (since the overtake happens during 2010 around November). Also note that I didn't include the solution to the fifth exercise because it's example 3 of section 3.5 (page 178).
