Office Tile Choice - posted November 15, 1999 I need your help to determine which tile I should purchase to cover the floor in my office. I have found two patterns that I particularly like. The first pattern has light green triangles on a dark green background. These 3 inch by 3 inch tiles come boxed in packs of 75 with a cost of $55.21 per pack. The second pattern is a dark green diamond on a light green background. These 9 inch by 9 inch tiles come 12 tiles to a pack and cost $75.89 per package. My office measures fifteen and a half feet by twelve and a quarter feet. That means that some of the tiles will need to be cut. When a tile is cut, only one portion of that tile may be used. There may be some wasted tile pieces, but the pattern on the floor will match. Since I can't decide which pattern I prefer, my husband suggested we go with the less expensive tile. Which tile is less expensive? In your explanation be sure to include the following information: The number of 3 inch tiles needed to cover the floor. The total cost of the 3 inch tiles. The number of 9 inch tiles needed to cover the floor. The total cost of the 9 inch tiles. Bonus: To have the flooring installed, the cost is $175 plus seventeen cents per installed tile. There is an additional charge of $2.95 for each tile that must be cut. After considering the installation costs will my flooring choice need to change? What is the total cost of the less expensive flooring, including installation? Please be sure to fully explain your bonus answer. |
