Step-by-step explanation:
So, for 60 square feet they charge = 287
So, for 1 square foot they charge = 
If they charge the installation fee this becomes = 
We can write an equation to calculate cost by using this 
Where x is the amount of square foot
It’s the third answer
(2x + 5) x ( 3x -4)
The formula of a slope:

We have the points (1, 4) and (1, -3). Substitute:

DIVISION BY ZERO!!!
Answer: The slope is undefined.
It's a vertical line x = 1.
224,640
(8,000*1.17)(6*4) due to quarterly interest
(8,009*1.17)(24)
(9,360)(24)
9,360*24=224,640
