Text: College Mathematics for Business, Economics, Life Sciences, and Social Sciences, 11th ed.; Barnett, Ziegler, and Byleen; Pearson Prentice Hall; 2008

Calculator: TI-83

Prerequisite: MAT 100 or ACT/SAT Math score of 22/510 or higher.

### COURSE OBJECTIVES

MAT 131 includes topics from mathematics of finance, systems of linear equations, matrices, linear programming, sets, counting, and probability with applications to business and economics. A student successfully completing every aspect of this course should be able to

• solve finance problems involving simple or compound interest.
• solve finance problems involving annuities.
• perform basic matrix operations.
• solve systems of linear equations using Gauss-Jordan elimination.
• solve systems of linear equations using matrix equations.
• use the simplex method to solve maximization problems with ≤ problem constraints.
• use the simplex method to solve minimization problems with ≥ problem constraints.
• solve counting problems.
• solve probability problems.
• find the expected value of a random event.

### HANDOUTS

Handouts are indicated by a icon on the tentative course schedule below. The icon is a link to a Microsoft Word document that you should print out and bring to class with you. You should get in the habit of bringing your TI-83 calculator and the day's handout to class every time we meet.

After we have discussed the material for the day, the icon will become a icon which is a link to a Word document that details the solutions to that day's example problems.

Grades will be based on the following activities:

1. Four exams worth 100 points each. The first three exams will be given during regular class time and the fourth exam will be given during the normal final exam period. You'll find a links to practice tests on the tentative course schedule below.

2. Eleven laboratory assignments worth 10 points each. For each assignment, you complete an Excel workbook using a computer in one of the computer labs or your own Windows computer (sorry, Macs won't work). Each assignment is indicated by a icon in the tentative course schedule given below. The icon is shown on the date the assignment is given. The icon is a link to the assignment webpage. The assignment is due at the beginning of the next class period. Lab assignments turned in late will receive no credit unless I determine that there were extenuating circumstances. The two lowest lab scores will be dropped.

3. Ten quizzes worth 10 points each. A quiz is indicated by a icon in the tentative course schedule below. The icon is shown on the day of the quiz. The icon is a link to a sample quiz. Quizzes are given at the beginning of the class period and all quizzes will be collected at the same time. Consequently, students arriving to class late will have less time to complete the quiz. The lowest quiz score will be dropped.

4. Thirty-eight homework assignments worth 5 points each. Homework assignments are indicated by a icon. The icon is shown on the date the assignment is given. The icon is a link to the assignment web-page. The assignment is due at the beginning of the next class period. Homework assignments turned in late will receive no credit unless I determine that there were extenuating circumstances. The 4 lowest homework scores will be dropped.

Letter grades are assigned on the basis of the number of points earned out of the 750 points possible:

 Grade Points A 698 - 750 A- 675 - 697 B+ 653 - 674 B 623 - 652 B- 600 - 622 C+ 578 - 599 C 548 - 577 C- 525 - 547 D 450 - 524 F 000 - 449

### ATTENDANCE POLICY

1. All students are expected to attend class as well as complete assignments and readings outside of class.

2. If a student misses a class, the individual is responsible for the work missed.

3. In the case of: (a) hospitalization or serious illness (as determined by a physician), (b) Asbury University approved group event or travel (i.e., class trip, athletic team trip, etc.), (c) death or serious illness of family member, or (d) other unusual circumstance, the registrar will issue an excused absence (with permission to make up work) to be presented to the instructor.  Students may not be penalized for any absence approved by the Registrar’s Office.  Decisions regarding absences resulting from such circumstances as travel difficulties, bad weather, conflicting schedules, oversleeping, minor sickness, doctor or dentist appointments, job interviews, discretionary trips (such as weddings), and family responsibilities will be left to the discretion of the instructor.

4. A student may miss without excuse 4 class hours per 3 credit-hour class.
Example: A 3 credit hour class that meets MWF may miss 4 class periods
A 3 credit hour class that meets TR may miss 3 class periods

5. A student may miss without excuse 1 class hour per 1 credit-hour class.

The work (homework, Excel assignment, quiz or test) submitted by a student is expected to be the product of the student alone. In this course, cheating includes unauthorized collaboration (giving or receiving help from some person) and unauthorized access to sources (including notes, cheat sheets, digital documents, and so on). Incidents of academic dishonesty will be recorded in your permanent file. In addition, the following penalties will apply:

• The first offense will result in a grade of 0 on the work in question and you will be required to meet with the Academic Dean.
• The second offense will result in a grade of F for the course and you will be required to meet with the Academic Integrity Committee.
• The third offense will result in suspension from the university.

You can find Asbury University's complete academic integrity policy in the university bulletin at the following link:

### TUTORING SERVICES

The Center for Academic Excellence has tutors available to meet with you to work on a full range of academic meets. If you find yourself struggling in any of your classes, please contact them, and they will work to match you with a tutor ASAP. Services are all FREE, so take advantage of the opportunity! If there is not currently a tutor for the specific class for which you are requesting assistance, the CAE will do its best to work with your professor to find a student who can assist you.

To apply for a tutor, please locate the application on the CAE website http://www.asbury.edu/academics/cae.

The CAE is located in KL 139 (basement of Kinlaw Library). You can send emails to tutoring@asbury.edu or call at campus extension 2196.
