John needs to buy at least 100 tiles to redecorate his bathroom. The tiles are sold in packs of 6.

AnnyKZ [126]

Answer: $n\geq17$

Step-by-step explanation:

Let n= Number of packs John needs.

Tiles in 1 pack = 6

Tiles in <em>n</em> pack = <em>6n</em>

If he needs at least 100 tiles.

then

6n ≥ 100

$\Rightarrow\ n\geq100\\\\\Rightarrow\ n\geq\dfrac{100}{6}\\\\\Rightarrow\ n\geq\dfrac{50}{3}\\\\\Rightarrow\ n\geq16.67\\\\\Rightarrow\ n\geq 17$

The required inequality: $n\geq17$
