A light bulb manufacturer found that 3 out of every 268 light bulbs in every batch were bad. If they produced 22,158 light bulbs, how many are bad?(1 point) light bulbs are bad.
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.
