82 light bulbs are bad.
To calculate this, first find the proportion of bad light bulbs in a batch:
3/268 = x/22158
Cross multiply:
268x = 3 * 22158
x = 3 * 22158 / 268
x = 22158 / 89
x ≈ 248.7
Since you can't have a fraction of a light bulb, round up to the nearest whole number:
82 light bulbs are bad.
