A quality-control inspector examined 100 light bulbs and found 7 defective. At this rate, how many defective bulbs would there be in a lot of 2500 bulbs?

1. Keeping on mind that the inspector examined 100 light bulbs and found 7 defective, you can calculate the number of defective bulbs that there would be in a lot of 2500 bulbs as following:

- Let's call the number of defective bulbs that there would be in a lot of 2500 bulbs [tex]x[/tex].

- Then, you have:

[tex]\frac{100}{7}=\frac{2500}{x}[/tex]

- Solve for x:

[tex]x=\frac{2500*7}{100}[/tex]

[tex]x=175[/tex]

2. Then, there would be 175 defective bulbs in a lot of 2500 bulbs.
