Since it takes more space to grow a silver bell than a cockleshell, Mary will have more room to expand her planting of silver bells as the garden size increases from 90 to 120 square feet. However, she will still have room to increase her planting of cockleshells as well. Therefore, she will plant more of both types of flowers, making choice B the best answer.
