Step-by-step explanation:

30 are unusable in 200. So how many are unusable in 17,000??

We can set up a ratio and figure out the answer right away! Let x be the number of unusable bolts in 17,000, so we can write:

$\frac{30}{200}=\frac{x}{17,000}\\200x=30*17000\\200x=510,000\\x=\frac{510,000}{200}\\x=2550$

THus, number of unusable bolts is 2550. B is right.
