Write a system of four inequalities to describe the situation.

Question

A farmer will plant corn and soy on his farm this year. He has a total of 25 acres availlable for planting . Each acre of corn cost $350 to plant ,and each acre of soy costs $150 to plant. his costs must be no more than $5250. Let x be the number of acres of corn to be planted and let y be the number of soy to be planted. Write a system of four inequalities to describe the situation. Then graph the system.

Answer 1

x + y ≤ 25

 

350x + 150y ≤ 5250

 

I guess I'm missing something because I don't see the need for 2 additional inequalities.
