Answer 1

To find the printing rates for black-and-white and color pages, we can calculate the pages per minute for each:

1. Black-and-white pages:

   • The printer prints 48 black-and-white pages in 1.5 minutes.
   • Rate = Total pages / Time = 48 pages / 1.5 minutes = 32 pages per minute.

2. Color pages:

   • The printer prints 20 color pages in 2.5 minutes.
   • Rate = Total pages / Time = 20 pages / 2.5 minutes = 8 pages per minute.

So, we have:

• The printer prints 32 pages per minute in black-and-white.
• The printer prints 8 pages per minute in color.

The correct answer is:

• C. 32 pages per min of black/white AND 8 pages per min of color.
