You can put this solution on YOUR website! The total cost is $5120. Of this amount the material cost is $2840. This means that the installation cost will be $5120 - $2840 = $2280.
This $2280 represents the total floor area x $1.90 per square foot.
ie total floor area = $2280 / $1.90
=1200 square feet
You can put this solution on YOUR website! Define the following variables:
Total Cost T=5120
Total Installation Cost = I
Materials Cost M=2840
Area of Living Room = A
Installation Cost/ft^2 C=1.9
-------------------
The total cost for the job (T) can be expressed by the following equation:
--------------------
Now that you know the total installation cost, you can apply the following formula to determine the area of the living room (A).
Substitute previous found value for I:
