Cynthia’s broker charges her a commission of $88 for every $1000 of stock bought or sold. Cynthia bought 2,000 shares of Ombor Medical Supplies at $35.49 apiece. As the price rose and fell, she sold off part of her holdings. When the price rose to $48.57, she sold 600 shares. The price fell somewhat to $46.10, so she sold 1,150 of her shares. When the price climbed to $53.46, she sold off the remainder of her holdings. How much profit did Cynthia make in total?
