8minutes

Step-by-step explanation:

Total pages printed = 115pages

Since there are 35pages already on the tray before the printing commences, the additional number of pages printed will be 115-35 = 80pages

If 10pages is printed in one minute, 80 pages will be printed in (80/10) minutes which is 8minutes.

This means that the printer has been running 8minuutes.

Andres Morton · Answer 2

8 minutes.

Step-by-step explanation:

To calculate the time, we must calculate the number of sheets that will be printed, which in this case would be 115, which is the total minus 35 that there were, therefore:

115 - 35 = 80

That is, it printed 80 pages and to calculate the time we must calculate by the amount it prints per minute, that is 10

80/10 = 8

in other words, it takes a total of 8 minutes.
