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

`6/200=x/(10,280)`

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

`((6)(10280))/200=((x)(10280))/10280`

`x=((6)(10280))/200=308.4`

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