Solve.Marcus is planting a section of garden with tomatoes and cucumbers. The available area of the section is 150 square feet. He wants the area planted with tomatoes to be more than 
of the area planted with cucumbers. Write a system of inequalities to describe the situation. Let x represent the area (in square feet) planted in tomatoes and y represent the area (in square feet) planted in cucumbers.
A. x + y ? 150, x < 0.25y, x ? 0, y ? 0 B. x + y ? 150, x > 0.25y, x ? 0, y ? 0 C. x + y ? 150, x > 25y, x ? 0, y ? 0 D. x + y = 150, x ? 0.25y, x ? 0, y ? 0
