Question

lena wants to tile her kitchen floor, which has an area of 131 square feet. the 1 - foot square tiles she wants to use sell in packs of 5 tiles. what is the fewest number of packs of tiles she can buy to tile the entire floor?
27 packs of tiles
26 packs of tiles
55 packs of tiles
23 packs of tiles
31 packs of tiles

Explanation:

Step1: Calculate total tiles needed

The floor area is 131 square feet, and each tile is 1 square foot, so we need 131 tiles.

Step2: Divide total tiles by tiles per pack

Each pack has 5 tiles. So we calculate $131 \div 5 = 26.2$. Since we can't buy a fraction of a pack, we need to round up to the next whole number. So we need 27 packs? Wait, no, wait. Wait, 26 packs would give $26\times5 = 130$ tiles, which is not enough. 27 packs give $27\times5 = 135$ tiles, which is enough. Wait, but let's check the options. Wait, the options include 27, 26, etc. Wait, maybe I made a mistake. Wait, 131 divided by 5 is 26.2. So we need to round up to 27? But wait, the options: let's check the options again. Wait, the options are 27, 26, 55, 23, 31. Wait, 26 packs would be 130 tiles, which is less than 131. So we need 27 packs. Wait, but maybe the original problem has a typo? Wait, no, let's recalculate. 5 times 26 is 130, which is less than 131. So we need 27 packs. So the correct answer is 27 packs of tiles.

Answer:

27 packs of tiles
