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?

Cynthia sold 600 + 1,150 = 1,750 shares, leaving 250 to sell. Her total sales were (600 × $48.57) + (1,150 × $46.10) + (250 × $53.46) = $95,522. Her purchase cost was 2,000 × $35.49 = $70,980, so the profit before commissions was $24,542. The commission is 8.8% of each transaction, so commissions on the $70,980 purchase and $95,522 in sales total $14,652.176. Subtracting those commissions gives a profit of $9,889.82, choice A.
