Workers Inc. just bought 10 boxes of pens to put in their storage room for employees to use as needed. Each box contains 30 pens

GenaCL600 [577]

Answer:

B. 204 pens

Step-by-step 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
