# FINITE MATHEMATICS FOR BUSINESS AND MANAGEMENT

COURSE DESCRIPTION:

While this course may be used to fulfill part of the six-hour general education
mathematics requirement for the A.S. degree at John A. Logan College, it is designed
students will be required to take a calculus course to complete their mathematics
sequences. This course will fulfill the mathematics requirement for the A.A. degree.
Topics covered include functions and lines, linear systems, linear programming, the
Simplex Method , mathematics of finance, set theory, and probability. This course is not
designed for mathematics or science majors. The Texas Instruments TI-83 graphing
calculator or a graphing calculator approved by the instructor is required for this course.

PREREQUISITES:

MAT 108 with a grade of “C” or higher or assessment

COURSE OBJECTIVES:

1. Construct cost, revenue, and profit functions and perform break-even analysis.
2. Solve straight -line depreciation problems utilizing linear functions.
3. Calculate future value and present value for simple interest accounts, compound
interest accounts, and annuities.
4. Calculate effective rate of interest for a compound interest account.
5. Calculate the point of equilibrium in supply and demand analysis.
6. Write the parametric form of an infinite solution to a system of linear equations.
7. Solve a system of linear equations using matrices and elementary row
operations.
8. Apply matrix operations in performing tests for equality, addition, subtraction ,
scalar multiplication, and matrix multiplication.
9. Calculate the inverse of a square matrix .
10. Utilize inverse matrices to aid in solving for the sector production levels that will
meet internal and external demands of a Leontief Input-Output model.
11. Calculate the feasible region and its corner points relating to a system of linear
inequalities involving two variables.
12. Use the feasible region and its corner points to solve a two- variable linear
programming problem.
13. Apply the Simplex Method to solve a linear programming problem involving
standard and mixed constraints.
14. Utilize the Dual to solve a linear programming problem.
15. Apply set operations and use Venn diagrams to aid in performing tests for
equality, unions, intersections, complements, and subset analysis.
16. Count the number of elements in a set using Venn diagrams, the inclusionexclusion
principle, the addition rule , the multiplication rule, tree diagrams,
permutations, and combinations.
17. Calculate regular and conditional probabilities using set counting procedures,
mutual exclusion, independence, the complement rule, the union rule, the
multiplication rule, and Bayes’ rule.

COURSE REQUIREMENTS:

Homework. Homework will be assigned at every class session. The student should
realize that, as a general rule of thumb, a minimum of two hours of study outside of
class is required for every one hour of class time. This course will require a minimum of
twelve to twenty-two hours per week of outside class work.

Attendance. Attendance to this class is both expected and required. John A. Logan
College’s attendance policy will be enforced:

A. Students are expected to attend all scheduled class periods for the courses in
which they are enrolled unless they are participating in a scheduled, supervised
college trip or function. There are no excused absences or minimum number of
class “cuts.” All absences must be made up in a manner acceptable to the
instructor.

B. A student who is absent from class for three consecutive meetings or who is
excessively absent as defined by the instructor (more than 5 absences), without
prior approval, may be required by the instructor to meet with the appropriate
administrator before being readmitted to the class. Students who claim illness as
a cause for excessive absences may be required to present a physician’s
statement before being readmitted to the class.

Required Materials. The textbook, along with the usual notebook, paper, pencils, etc.
represent the required materials for the class. The utilization of the Texas Instruments
TI-83 Graphing Calculator will be emphasized in classroom presentations as well as on
homework assignments and tests. Hence, the student is required to use the TI-83 on
appropriate assignments and should be knowledgeable of its workings. The functions
provided by the Texas Instruments TI-83 Graphing Calculator will be utilized
throughout the course and will be required for successful completion of certain
homework assignments and tests.

Student Success Center. Tutors may be obtained through the Student Success Center.
Contact the staff in C219 if this service is desired. John A. Logan College will make
reasonable accommodations for students with documented disabilities under Section
504 of the Rehabilitation Act of 1973, and the Americans with Disabilities Act of 1990.
Any student with a disability that may have some impact on work in this class, who feels
she/he needs an accommodation, should make an appointment with the Coordinator of
Services for Students with Disabilities on campus, Christy McBride, Room C219B, Ext.
8516. Before services can be provided, this advisor must determine eligibility and
register in advance of a school term with this office and to turn in a schedule
each term to ensure that there is every opportunity for success in this class.

English Writing Center/Tutoring: For assistance with writing assignments in any college
courses, students are encouraged to visit “The Write Place” in E109. English instructors
are available for one-on-one tutoring each semester during hours posted at the center.

Financial Aid. Students who receive financial assistance and completely withdraw from
classes prior to 60% of the semester being completed (approximately 2-3 weeks after
midterm) could be responsible to return a portion of their Federal Pell Grant award.
Prior to withdrawing from courses, students should contact the Financial Aid Office.

METHOD OF EVALUATION:

Evaluation will be made on the basis of:

1. A maximum of five 100-point exams that will be administered periodically over
the course of the semester.
2. A 200-point comprehensive final exam.

The combined average of the tests and the final exam will determine the student’s

No make-ups will be given on the tests. Students attending a required school-sponsored
activity must make arrangements with the instructor to complete the exam
before attending the obligatory event. Any answers, which have been copied from
someone else, will result in a zero for all parties involved.

Grades are assigned according to the following scale:

METHOD OF PRESENTATION:

Most instruction will be of the lecture-discussion type. Homework will be assigned
which, together with announced exams serve to amplify and clarify the classroom
discussions. Occasionally, topics will be assigned to be performed through independent
study. Ample opportunity will be provided for the student to meet with the instructor on
a one-to-one basis during office hours to clear up any difficulties that may arise.
