b. How many square feet are there in a square yard?
c. Find the total area to be carpeted in square yards.
d. Not everybody realizes this, but when you buy carpet, you pay for the estimated
amount, not the actual amount covering your floors. Considering that the
professional estimate for the carpeted area is 22 square yards, find the relative
difference between the estimate and the actual area of the carpeted portion of the
room. Write the relative difference as a percentage. Write a sentence explaining
what this tells us about how the estimate compares to the actual carpeted area.
e. If the family that owns the house in the diagram picked carpet that costs $25.25 per
square yard installed, how much would they have paid using the estimation by the
professional?
f. Use the actual difference between the estimate and the carpeted area to find the
dollar value of wasted carpet.
