 * __Big Idea:__** Many important practical and mathematical applications involve comparing quantities of one kind or another; it is important to know which method to use and how we should use them.
 * __Essential Question:__** What methods are there for comparing things?


 * __Notes from class:__**
 * A ratio is a percent that compares a number to 100
 * Make proportions to get a percent
 * To get a percent, covert ratios into a decimal form and then multiply by 100
 * __Problem 1.1- Writing Ads__

A) Describe what you think each of the fout statements means. Explain how each shows a comparison. Be sure to tell //what// is being compared and //how// it is being compared.** In the four statements the two cola companies are being compared. They are being compared by ratio, percentages, fractions and differences. Each of them are compared cola taste tests that say which cola is better.


 * B) Is it possible that all four advertising claims are based on the same data? Explain you answer.**

It is possible that all four advertising claims are based on the same survey data becuase all of them end up having a conclusion that BOLDA COLA is preffered more. Although they are in different forms of comparisons, they still mean the same thing are all equal to 60%.


 * C)** **Which comparison do you think is the most accurate way to report the survey data? Why?**

I think that the second comparison is the most accurate way to report the survey data. This is because when you add up the two results for the both companies you get the total number of people who were surveyed. That helps you analyze the result more better and gives you the actual outcome of the taste test.


 * D) Which comparison do you think would be the most effective advertisement for Bolda Cola? Why?**

I think think that the last comparison would definetely be the most effective advertisment because at one glance people would see that BOLDA COLA is better and its a very quick and clear way to figure that out.


 * __Problem 1.1 Follow-Up__**


 * Write two statements comparing the popularity of the two colas. Explain each statement you write.**

__Statement # 1__ In taste tests more than half of those tested preffered BOLDA COLA to COLA NOLA.

This statement concludes that BOLDA COLA is better but in a way that everyone can understand very clearly.

__Statement # 2__ In taste test 40% preffered COLA NOLA to BOLDA COLA which was preffered by 60%.

This statement concludes that BOLDA COLA is preffered more and by 20%.
