Question

Tony wants to plant no more than 400 acres of corn and soybeans. He earns $300 per acre of soybeans and $200 for corn. He needs to earn at least $60,000. Let X represents corn and Y represents soybeans. Write a system of inequalities that represent this situation.

Answer 1

In this item, we let x be the number of corns and Y represent soybeans. The sum of these variables is 400. This is represented by the equation,
                                             x + y = 400
The amount that needs to be earn by Tony is then represented by,
                                            200x + 300y ≥ $60,000
