**MAT 221 WEEK 2 ASSIGNMENT ( Inequalities ) ~ INTRODUCTION TO ALGEBRA**

**Inequalities**

Read the following instructions in order to complete this assignment, and review the example ow to complete the math required for this assignment:

- Read the article about Body Mass Index (BMI) on page 151 of
*Elementary and Intermediate Algebra*. Use the formula given using pounds and inches for finding the BMI at the end of the first paragraph in order to find the four intervals the article mentions:

- 17 < BMI < 22 might have a longer life span than average
- 23 < BMI < 25 probably not overweight
- 25 < BMI < 29.9 probably overweight
- BMI > 30 obese

You will use *your height*to plug into the formula to solve for W, the weight range that will go with each category. You may prefer to solve the formula for the variable W before plugging in values, which is fine.

- Write a two to three page paper that is formatted in APA style and according to the Math Writing Guide. Format your math work as shown in the Instructor Guidance and be concise in your reasoning. In the body of your essay, please make sure to include:

- Your solution to the above problem, making sure to include all mathematical work
- A discussion on the computed weight ranges and some reasons why they could be misleading
- An evaluation of the regions
*outside*of the “probably not overweight” range using both set notation and interval notation. Include a simple graph of the regions. (See Instructor Guidance example for some ideas of how to do this.) - The incorporation of the following five math vocabulary words into your discussion. Use
**bold**font to emphasize the words in your writing (**Do not write definitions for the words; but integrate them into your discussion**.):

- Inequality
- Equivalent
- Compound inequality
- Interval
- Infinity

**MAT 221 WEEK 3 ASSIGNMENT ( Two-Variable Inequality ) ~ INTRODUCTION TO ALGEBRA**

**Two-Variable Inequality**

Read the following instructions in order to complete this assignment, and review the example of how to complete the math required for this assignment:

- Read problem 46 on page 240 of
*Elementary and Intermediate Algebra*.

- Assign a variable to each type of rocker Ozark Furniture makes.
- Write a linear inequality which incorporates the given information of total board feet and the board feet required for each type of rocker.
- On scratch paper draw a graph of the inequality so that you have this visual to go by as you discuss the graph in your writing. A scanned copy of this graph may be attached with your essay, but is not required.

Write a two to three page paper that is formatted in APA style and according to the Math Writing Guide. Format your math work as shown in the Instructor Guidance and be concise in your reasoning. In the body of your essay, please make sure to include:

- Your solution to the above problem, making sure to include all mathematical work.
- A discussion on what this graph looks like. Include information about the intercepts, the type of line needed, direction of the line, and region(s) shaded to fulfill the inequality. Any details which are pertinent to know about the graph should be mentioned.
- An application of the findings in this graph. For example, pick a point in the shaded area and give its coordinates, and then discuss what those numbers mean in terms of rockers and board feet of lumber. Pick a point outside of the shaded area and do the same thing. Pick a point right on the line and discuss the same details.Be specific.
- An evaluation of the following: A chain furniture store faxes an order for 175 modern rocking chairs and 125 classic rocking chairs. Will Ozark Furniture be able to fill this order with the current lumber on hand? If yes, how much lumber will they have left? If no, how much more lumber would they need to fill the order?
