The bottom surface of the pool is flat and needs new tiles. If each tile covers 1/9 of a square yard and costs $3, what is the cost of the tiles to retire 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

The cost of the tiles to retile the bottom of the pool is $27.
