3 INTRODUCTION The videos that go along with this study guide were recorded in an actual MAT 0012, Developmental Arithmetic with Algebra class during the summer of If you have any questions or comments about the videos or this study guide, please contact Mr. Lloyd Harris at (850) ext or by at ROAD TO SUCCESS Since this course is an E-Learning course, the method of instruction is primarily a selfstudy one. You are expected to demonstrate sufficient self-discipline and self-motivation to complete all unit tests and the final exam within the designated time. To be successful, you should follow these steps: 1. Begin the lesson by looking at the objectives listed here in the study guide. The study guide follows the section numbers of the textbook. 2. Watch the video for the section you are studying. While watching the video, follow the study guide, answer the questions in the study guide, work the problems provided in the study guide, and take notes as if you were sitting in a classroom. Stop or pause the video as needed to catch up or copy something down. 3. Once you have viewed the video, look at the study guide and the textbook for further examples, steps or procedures, etc. 4. Try the homework. The answers to the odd numbered problems are in the back of the textbook. Some homework problems are explained on the videos for each section. The number of homework problems explained varies for each section. Homework is abbreviated H.W. on the videos. 5. Complete the homework, quizzes and reviews in MyMathLab for each test. 6. HOW TO STUDY FOR TESTS!!! The best way to study for a test is to take your objectives for each section and find corresponding problems from the homework. Take these problems and make yourself a practice test. Without looking at your notes, take the practice test. This will tell you where you are weak and need to study further. Do the review for the test in MyMathLab. 7. The Math Lab on campus provides free tutoring. 1

135 NOT ON THE VIDEO! Example1: Solve y = mx + b for m. y = mx + b y b = mx + b b y b = mx y b mx = x x y b = m x We are asked to solve for m. We need to get m by itself on one side of the equation and everything else on the other side. 1. Subtract b from both sides of the equation. This will isolate the mx term. 2. We need a positive one coefficient on m. 3. Divide both sides by x. Example 2: Solve P 2 l + 2w P 2l 2 P 2l 2 = for w. P = 2l + 2w P 2l = 2l 2l + 2w P 2l = 2w 2w = 2 = w 133

147 NOT ON THE VIDEO! Example 1: A set of golf clubs costs $266 after a 30% discount. Find the original cost. Let x represent the original cost. The amount of the discount is 0.30x. (original cost) - (discount) = (sale price) Therefore, (x) (.30x) = x = x = = The original cost is $380. Example 2: Mary wrote a check for $88.20 for a new dress. The tax rate was 5%. Find the price of the dress. Let x represent the price of the dress. The amount of the tax is represented by.05x.
