To find a percentage of a number, turn the percent into a decimal by dividing by 100, then multiply that decimal by the number.
82 ÷ 100 = 0.82
0.82 × 950 = 779
Now, to find the number of seats not occupied, you subtract the percentage that is occupied from the whole.
779 is 82% of 950, so 779 will be subtracted from 950
950 - 779 = 171
171 seats are not occupied.

First, let's find out how many of the seats are occupied.

82% of 950 = 0.82 * 950 = 779

So 779 seats were occupied, now subtract this from the total seats to find out how many seats are not occupied.

950 - 779 = 171

So 171 seats are not occupied.

Another way to do this is to find the percentage of seats that are not occupied.

82% are, so subtract it from the total, 100%

100% - 82% = 18%

Now find 18% of 950.

0.18 * 950 = 171
