Lecturer:      Graham Ellis
(ext: 3011, e-mail:graham.ellis(at)nuigalway.ie)

Tutor:           Fintan Hegarty

Text:             "Applied Mathematics for Business, Economics, and the Social Sciences"
by Frank S. Budrick

Assessment:
The course will be assessed by an exam at the end of Semester I (80%) and a mid-term class test (20%).
The exam and test  will assume that you have studied the homework sheets and past exam papers!

Course Description:

• Topic 1: Straight lines and Inequalities (Students will learn how to maximize 2-variable profit functions subject to linear constraints.)
• Topic 2: Systems of three or more linear equations and matrix methods. (Students will learn to solve systems of equations arising from resource allocation problems.)
• Topic 3: Interest rates and net present values. (Students will learn about the value of government bills, and how to compare simple business cash-flow models using net present values.)
• Topic 4: Descriptive statistics. (Students will learn to describe experimental data using medians, modes, means, percentiles, variances and histograms.)
• Topic 5: Probability. (Students will will learn to calculate the expected value of financial random variables, and learn to place financial values on information such as weather forecasts.)
