Answer:
Therefore, there are 9,117 more blue pens made than the red and green pens combined.
Explanation:
To find out how many more blue pens are made than red and green pens combined, we need to calculate the total number of red and green pens, and then subtract that from the number of blue pens.
Let's calculate the total number of red and green pens:
Red pens: 42,896
Green pens: 12,365
Total number of red and green pens: 42,896 + 12,365 = 55,261
Now, let's find out how many more blue pens are made than the red and green pens combined:
Blue pens: 64,378
Total number of red and green pens: 55,261
Blue pens - Total number of red and green pens: 64,378 - 55,261 = 9,117
