CCSS.Math.7.RP.3(NQ1c) Percent of Change

Dear Girls and Boys,

We are moving onward with Percent of Change.  Math often times names things as they are.... in this case, Percent of Change is where we will continue to work with Percent - divided by 100- but this time we will be looking at how things change- meaning: going up or down.  For example:  If there is a sale going on( my favorite time to shop), the price with go down after a certain percent it taken away.  This is Percent of Decrease! And the opposite: If I buy something at the store, I will have to pay more due to sales taxes. This is Percent of Increase!  There are formulas to help solve these, and I am thinking that you will catch on fairly easy as it is a very common thing to work on.  The third part of this lesson is Percent of Error.  This is the difference between the guess and actual amount.  It is figured just like Percent of Increase and Percent of Decrease.  Hang on, watch the videos and ask questions.  

Ask questions and come to class prepared to learn.

As always in MATH,
