Expert Answers

An illustration of the letter 'A' in a speech bubbles

Write this problem as a proportion: 6 bulbs are defective for every 200 bulbs, x bulbs are defective for every 10,280 bulbs.


To solve for x, multiply both sides by 10,280.



Thus 308.4 bulbs would be defective in a shipment of 10,280 bulbs.
