Dixon Orchards has purchased land on which to plant lime and orange trees. Each lime tree requires 100 square feet of area. Each orange tree requires 200 square feet of area. Dixon Orchards determines that they have no more than 3,100 square feet of land on which to plant the lime and orange trees. If x represents the number of lime trees and y represents the number of orange trees, which inequality can be used to describe the situation? 100x + 200y < 3,100 ⊝ 100x + 200y ≤ 3,100 ⊝ 100x + 200y > 3,100 ⊝ 200x + 100y ≤ 3,100 CLEAR ALL ❮
