Two years ago, you invested $10,000 by buying 250 shares ( $28 per share NAV) in the Canon Ball Mutual Fund, an aggressive growth no-load mutual fund. Last year, you made two additional investments of $1,800 each ( 60 shares at $30 and 72 shares at \$25). You reinvested all of your dividends. So far, the NAV for your investment has risen from $28 per share to $35. Late in the year, you sold 75 shares at $35. (a) What were the proceeds from your sale of the 75 shares? (b) Investors can use the Internal Revenue Service's "average-cost basis method" to determine the average price paid for one share. Begin by calculating the average price paid for the shares. In this instance, the $13,600(10,000+1,800+1,800) is divided by 382 shares ( 250 shares +60 shares +72 shares). What was the average price paid? (c) To finally determine the average-cost basis of shares sold, you multiply the average price per share times the number of shares sold -in this case, 75. What is the total cost basis for your 75 shares? (d) Assuming that you have to pay income taxes on the difference between the sales price for the 75 shares and their cost, how much is this difference
