Answer: A. divided the difference of the two quantities by the sum of the two quantities.
===================================================
Explanation:
The difference of the quantities is 20-15 = 5
The sum of the quantities is 20+15 = 35
Dividing those results leads to 5/35 = 0.142857 which rounds to 0.1429
That converts to 14.29%
This is likely the path Adam took. This path is incorrect. The correct steps are shown below
---------------------
Difference = 20-15 = 5
Divide the difference over the original quantity
5/20 = 1/4 = 0.25 = 25%
We have a 25% decrease because the new quantity (15) is smaller than the old quantity (20)
----------------------
Here's another way to approach the problem
A = old value = 20
B = new value = 15
C = percent change
C = [ (B-A)/A ] * 100%
C = [ (15-20)/20 ] * 100%
C = (-5/20)*100%
C = -0.25*100%
C = -25%
The negative C value means we have a negative percent change, ie we have a percent decrease. So this is another way to get a 25% decrease.

Answer:
y = -2x + 3
Step-by-step explanation:
<u>Step 1: Find out what each part of slope intercept form is</u>
Slope Intercept Form: y = mx + b
<em>m is the slope</em>
<em>b is the y-intercept</em>
<u>Step 2: Plug in the information into the formula</u>
m/slope = -2
b/y-int = 3
<em>y = -2x + 3</em>
<em />
Answer: y = -2x + 3
