82 light bulbs are bad.
First, calculate the ratio of bad light bulbs to total light bulbs in a batch: 3/268 = 0.011194
Next, multiply this ratio by the total number of light bulbs produced: 0.011194 x 22,158 = 248
Therefore, 82 of the 22,158 light bulbs produced are bad.

bulbs, how many are bad? (1 point)
