Problema Solution
You are buying carpet to cover a room that measures 9 feet by 10 feet. The carpet costs $25 per square yard. How much will the carpet cost?
Answer provided by our tutors
1 yd = 3 ft
1 yd^2 = 9 ft^2
1 ft^2 = 1/9 yd^2
The area of the carpet is:
9*10 = 90 ft^2 = 90*(1/9) yd^2 = 10 yd^2
Since the cost of 1 yd^2 is $25 the cost for 10 yd^2 is: 25*10 = $250.
The carpet will cost $250.
