In this and future Instructor Graded Assignments you will be asked to use the answers you found in the Unit 1 Assignment.
Note: For these questions you need to cite a reliable source for information, which means you cannot use sites like Wikipedia, Ask.com®, and Yahoo® answers. If you do use those sites the instructor may award 0 points for your response.
The Assignment problems must have the work shown at all times. The steps for solving the problems must be explained. Failure to do so could result in your submission being given a 0. If you have any questions about how much work to show, please contact your instructor.
Assignments must be submitted as a Microsoft Word® document and uploaded to the Dropbox for Unit 2. Type all answers directly in this Assignment below the question it applies to. All Assignments are due by Tuesday at 11:59 PM ET of the assigned Unit.
Finding the National Average Price for Gas
These first few questions will require you to use the internet to search for the national average price for gas. Remember to use a scholarly site for information.
List the website(s) you visited here: http://fuelgaugereport.aaa.com/todays-gas-prices/.com
1. (2 points): What was the average price of a gallon of gas 1 year from when your business math class started?
A month ago the national average gas price was 2.035
2. (5 points): You have $50 on hand and need to buy gas. How many gallons of gas can you buy (using the value you reported in Question 1.)If i had 50 on hand i would be able to purchase 24.57 gallons of gas for a total of 49.99995 which would be 50.00.
3. (5 points): If gas prices were to drop 10% from the current price, how much would a gallon of gas cost now?
Current national price per gallon of gas is 2.328. The difference from the price of gas a month ago vs. the cost of gas per gallon currently. The price of gas had increased by about 12.5%.
4. (5 points): Using the average for 1 year ago, and the average for 6 months ago, calculate the percent increase or decrease in the price of a gallon of gas over that 6 month time span.
A year ago 3.426 and 6 months ago was 3.65 so there was a decrease by 6.5%.
Finding the National Average for Food for One Person
Questions 5, 6, and 7 will require you to search for the national average for food for one person. Remember to use a scholarly site for information.
List the website(s) you visited here: http://www.cnpp.usda.gov/Publications/FoodPlans/2012/CostofFoodJan2012.pdf http://www.loweryourspending.com/average-cost-for-food-per-month-for.one .person.html .com 5. (3 points): What was the national average for food for a month for one person, one year ago from the date the class started? Use the average for a 35-year-old male, and if multiple figures are given for that gender and age, use the highest number.
National average for food for a month for one person=287.00
Average for a 35 year old male is 292.30
6. (5 points): If this person lives in a state with a 7% sales tax on all food purchases, how much will they need to spend on food for one year?
$287.00 * 0.07 =$20.09
$287+20.09=$307.09
$307.09 * 12 =$3,685.08 a year
7. (5 points): Create an equation you could use to calculate the cost one person spends on food for a year (assume no tax on the food), using this site. Your equation must work for any age range, and any gender now.
Essay Question
(15 points)
8. Using the internet, find a website where a linear equation is used. Using that website as a source, write a ¾ - 1 page essay response in which you discuss how the equation was used, if it was used correctly, and what solutions to the equation mean (in other words, why are you using the equation in the first place? What is the solution supposed to tell you once you find it).
A linear equation is a mathematical expression that has an equal sign and linear expressions. A linear expression is a mathematical statement that performs functions of addition, subtraction, multiplication, and division. When solving a linear equation, there are steps to follow that will get you to the correct answer. Once you solve for the variable, always plug that number back into the equation to check for accuracy. Let’s try an example and work through the linear equation together by following these steps. Find x if: 2x+4=10. The first step is to isolate “x” to one side of the equation by subtracting 4 from both sides. 2x+4-4=10-4, which you give you 2x=6. The next step is to get the x by itself by dividing both sides by 2. 2x/2=6/2 and that leaves us with x=3. The final step is to plug the 3 into the x variable to make sure we have the correct answer.
Requirements for essay
Write your essay in this document – do not save it in a separate file.
You must clearly state your position with well-structured paragraphs using proper grammar, spelling, and sentence structure.
This is not an “opinion” question – you must offer evidence to support your position, using properly cited sources.
Your answer must be between ¾-1 page in length.
You must cite and reference at least one source (book, website, periodical) using APA format. The required website counts as one source.
You may submit your Assignments to the Math Center for review. Tutors will not grade or correct the Assignment, but they will provide guidance for improvement. Tutors will not, however, help you find web sites for the Assignment.
Be sure to submit Assignments early enough to receive feedback and make corrections before the Assignment due date (24 hour turn-around times Monday-Thursday and 48 hour turn-around times on weekends are typical).
Email Assignments to: kumc@kaplan.edu. Please put “MM255 Assignment Review” in the subject line of the message.
