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..
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.
