Answer:
B. 204 pens
Explanation:
If you have 10 boxes of 30 pens each, the problem would be like so:
10 x 30 = 300
Now, since we have 32 workers that each take 3, this turns into:
32 x 3 = 96
Finally, because 300 is the total amount of pens and 96 is the amount taken, we just subtract to get:
300 - 96 = 204 pens
