Answer:
3630 dollars
Step-by-step explanation:
First, we need to find the area of the the room floor. To do this, we need to do 12 × 10 because 12 is the length and 10 is the width. 12 × 10 is 120. We also know that each square yard of carpet costs $30.25. We now have to multiply 120 × 30.25 because the room is 120 square feet large. 120 × 30.25 = 3630, so the carpet costs $3630.
