The bottom surface of the pool is flat and needs new tile. If each tile covers1/9 of a square yard and costs $3, what is the cost of the tiles to retile the bottom of the pool?
Each tile covers 1/9 of a square yard. It means that you need 9 tiles to cover the bottom surface of the pool. And we know that each tile costs $3. We have to multiply $3 by 9: The cost: 9 * $3 = $27 Answer: The cost of the tiles to retile the bottom of the pool is $27.
