Quantitative Reasoning- Unit 6 Growth Models
This project is very unique. There is no right or wrong answer and you will not be graded on the correctness of your answer. However, you will be graded on identifying the assumptions that you will need to make, the calculations once the assumptions are made, the correct conversions where needed, and presentation of the logic of how you arrived at your answer.
PROBLEM NUMBER 1
During a one year time period, how many gallons of water would the average household save by using an efficiency washer vs a regular washer? Is this one year savings more or less than the amount of water an average person drinks in a lifetime? Explain and show your assumptions, calculations, and conversions.
Consider it to be essentially 2 separate problems:
1. How much water is saved in a one year period when using an efficiency washer vs regular washer – answer based on your assumptions and calculations for full credit
2. How much water does an average person drink in a lifetime – arrive at this answer based on your assumptions and calculations
3. Compare the answers to those 2 questions to arrive at your conclusion
Below are 2 pieces of information that you might find helpful
there are 128 oz in a gallon
there are 365 days in a year and also 52 weeks in a year
1: How much water is saved in a one year period when using an efficiency washer vs regular washer.
PROBLEM NUMBER 2
Which amount of time is greater for the average person? The total time spent on his/her cell phone in a year’s time or the total time spent waiting in line when shopping in a lifetime?
Consider it to be essentially 2 separate problems just as in problem 1 and arrive at your conclusion.
You need to make assumptions, conversions, and math calculations to arrive at your answer. You will not be graded on the accuracy of your assumptions. You will be graded on the process at arriving at your answers, the correct conversions once you make your assumptions, and your logic/thought process in arriving at both answers. If you choose to research data for this project, that is fine but there is no need to site your references.
