Question

A hotel has 480 rooms. Of these rooms,
are non-smoking. How many rooms are smoking?

Answer 1

The number of smoking rooms
`N_s = (480(100-x))/(100)`, in which x is the percentage of non-smoking rooms.

Explanation:

We are given a percentage of rooms that are non smoking, lets say x%, and (100-x)% will be smoking rooms. The number of rooms which are smoking is the total number of 480, multiplied by (100-x) and divided by 100.

Then:

`N_s = (480(100-x))/(100)`
