The percent of change tells us how much something has changed in comparison to the original number.

There are two different methods that we can use to find the percent of change.

$$\frac=\frac$$ $$\frac\cdot =\frac\cdot b$$ $$a=\frac\cdot b$$ x/100 is called the rate.

$$a=r\cdot b\Rightarrow Percent=Rate\cdot Base$$ Where the base is the original value and the percentage is the new value.

We begin by subtracting the smaller number (the old value) from the greater number (the new value) to find the amount of change.

$0-150=90$$ Then we find out how many percent this change corresponds to when compared to the original number of students $$a=r\cdot b$$ $=r\cdot 150$$ $$\frac=r$$ $[[

$$240-150=90$$ Then we find out how many percent this change corresponds to when compared to the original number of students $$a=r\cdot b$$ $$90=r\cdot 150$$ $$\frac=r$$ $$0.6=r= 60\%$$ We begin by finding the ratio between the old value (the original value) and the new value $$percent\:of\:change=\frac=\frac=1.6$$ As you might remember 100% = 1.

Many percentage problems are really "two-part-ers" like this: they involve some kind of increase or decrease relative to some original value.

Once you have an equation, you can solve it and find the unknown value.To do this, think about the relationship between multiplication and division.Then you'll need to pick a variable for the value you don't have, write an equation, and solve for that variable.The format displayed above, "(this number) is (some percent) of (that number)", always holds true for percents.In any given problem, you plug your known values into this equation, and then you solve for whatever is left.In the above example, I first had to figure out what the actual tax was.
