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..

Answer 1

83 light bulbs are bad.

To solve this, first find the ratio of bad light bulbs to total light bulbs in a batch:

3 bad light bulbs / 268 total light bulbs = x bad light bulbs / 22,158 total light bulbs

Cross multiplying gives:

3 * 22,158 = 268x
66,474 = 268x
x ≈ 247.94

Since you can't have a fraction of a light bulb, you round up to the nearest whole number. Therefore, approximately 248 light bulbs are bad in the batch.
