Answer:
pages
Step-by-step explanation:
Method 1: Working with minutes
Let us assume that, Sandra's printer can print x pages in 1 minute.
Then we can write the equation:

Or

Method 2: Working with seconds
If 5 pages corresponds to 40 seconds, then we can write: 
Let y corresponds to 60 seconds (1 minutes).
Then:

We rewrite as fraction:

Multiply both sides by:




x= wildfires in 2003
163,476= 4x - 12,520
(163,476 + 12,520) / 4
x = 43,999 your answer is 43,999
