Answer:
The black-and white printer print can print 15 pages per minute.
Step-by-step explanation:
The given modeled equations are
3b + 5c = 70...(i)
6b + 9c = 135...(ii)
where b is the number of pages per minute of the black-and-white printer and c is the number of pages per minute of the color printer.
From equation (i), we have
Now, substitute the value of b in equation (ii), we have
By using equation (iii), we have
Hence, the black-and white printer print can print 15 pages per minute.
