Answer: Option 'A' is correct.
Explanation:
Since we have given that
0.5N+ 2.5M ≤ 6000
Number of newspaper sold = 8000
We need to find the possible number of magazines that to be sold.
Put the value of N = 8000.
So, we get that

so, the company can print 800 magazines at most.
Hence, option 'A' is correct.
