Answer:
the answer to this is D
Step-by-step explanation:
1 is 55
2 is 110
4 is 220
For this case we have that by definition, the equation of a line in the slope-intersection form is given by:

Where:
m: Is the slope
b: Is the cut-off point with the y axis
According to the data of the statement we have to:

Then, the equation is of the form:

We substitute the point
and find "b":

Finally, the equation is:

To graph we place the points
and
on the coordinate axis and join the points by a line.

The graphic is attached.
Area of the room = 14*15 = 210 ft^2
Cost padding = 210*89 = 186.90
Cost of carpet = 210 * 2.99 = 627.90
Perimeter of the room = 2*15 + 2*14 = 58 ft
Cost of strip = 58*0.19 = 11.02
Total cost of supplies = 186.90 + 627.90 + 11.02 = 825.82 Answer
