Kali invested in 200 shares of DEF Inc. at $⁢45 per share. After holding the stock for a year, she sold 150 shares at $⁢50 per share and the remaining 50 shares at $⁢40 per share. Calculate the total capital gain or loss from these sales.

Kali’s total purchase cost was 200 × $45 = $9,000. Her sale proceeds were (150 × $50) + (50 × $40) = $7,500 + $2,000 = $9,500, so she had a gain of $9,500 − $9,000 = $500. The correct choice is C, gain of 500 dollars.
