Kipish [7]

Answer:

$355.47 cents.

Step-by-step explanation

since you want to find the square footage of the entire room, hence Home Depot costs $3.40 per square foot, you would clearly need to find the area.  Basically find what 8.5 * 12.3 is and then multiply that number by 3.40. Once that is done, put a dollar sign on the answer and BOOM, you got it. :)

so $355.47 cents.
