Final answer:
The color printer prints 2.25 pages per minute.
Step-by-step explanation:
To find the number of pages the printer prints per minute, we can divide the number of pages printed by the number of minutes it takes. In this case, the color printer prints 9 pages in 4 minutes. So, to find the number of pages it prints per minute, we divide 9 by 4.
9 pages / 4 minutes = 2.25 pages per minute.
Therefore, the answer is Option A) 2.25 pages per minute.
