The total cost the farmer needs to pay in fertilizer is $8412, and he will also pay $12.10 per acre in order to harvest it.
Since the total size of crops is 160 acres, he will pay 160 times 12.10.
The amount p he needs to receive should be greater than the sum of all these costs, so we can write the following inequality:
[tex]p>12.10(160)+8412[/tex]
Therefore the correct option is the fourth one.
