First, multiply 20 x 25 to find the amount of chairs per section:
20 x 25 = 500
Now, multiply 500 x 4 to find the total amount of chairs for 4 sections:
500 x 4 = 2000
Hope this helps!! :)

Answer:
slope = -1
Step-by-step explanation:
First, you need to know the slope formula: <u>y2 - y1</u>
x2 - x1
Now recognize the first point (-2,3) as (x1,y1) and the second point (2,-1) as (x2,y2)
Now that you have done that, plug in the numbers into the slope equation.
Which should look like this: <u>-1 - 3</u>
2 - -2
Now that your equation looks like this, recognize the denominator, we should know that a negative plus a negative equals a positive. So instead of subtracting the denominator of the equation, we are going to add the two numbers together, because x1 is negative. Now solve, you should get the answer -1.
<u>-1 - 3</u> <u>-4</u> = -1
2 + 2 4
Hope this was helpful!
