If you are in need of a video tutorial on "Solving Systems of Equations Using Substitution click on the video link found HERE!  There are three parts.  You will do well to watch the first two parts.

Real World Math-Did The Government Get It Wrong?

Proportions!  We have been looking at how to use them since Chapter 5.  Did the creator of this graphic from the President's State of the Union from January 25 get it wrong.  Is the United States circle too big?



How would we use a proportion to determine if the size of the presumed circle is correct for the United States?

Algebra Used In Real Life

Jim Cramer "Mad Money" explains how (very quickly, you must catch it at 5:30 of the video) ALGEBRA is used in predicting where the price of a stock is going to go!  He states that the Multiple times the Earnings Estimate = Where the stock price is going to go.

You may not care about the stock market or have any plans to be a business person, but once again ALGEBRA is present in every day life.  Watch the video from the beginning or skip to 5:30 to hear Jim talk about this!


So what happened:  Kimberly Clark posted a 14.47 earnings per share or multiple.  We multiple that by the Earnings Estimate of 4.42 and obtain an answer of 63.9574 which is the "Where the price is going to go"  The price right now is $64.14 which means that the price has exceeded the algebraic formula.  However, this could be a quick reaction to good news as there was a slight increase in revenue.  See picture below...

Bottom Line:  Algebra is present and STATED by a person in business!!!

10 Billion App Follow Up


See original article!

We were correct.  According to this site, as of 2:30 P.M. January 19, the prediction is that on Saturday, January 22 around 4:00 P.M. will be the exact time.

Our class predicted using a proportion last Friday that the 10 billionth app would be downloaded on Saturday, January 22 around midnight.  Only 8 hours off.

Real Math.  Real Life.  Real Fun...More fun than counting the number of black beans among white beans!

Apple's 10 Billion App Download

After viewing this counter

One class predicted that it would reach 10 billion on Saturday January 22 around midnight.  A later class noticed that the speed at which the downloads was occurring were increasing.  We timed per 1000 downloads.  If this is the case, the 10 billionth download should occur around Friday January 21 at roughly 2 in the morning.

Real problems using real proportions!
