Mutual Fund Sales

Two years ago, Izabella Martinez, from Atlanta, Georgia, invested $1,160 by buying 145 shares ($8 per share NAV) in the Can't Lose Mutual Fund, an aggressive growth no-load mutual fund. Last year, she made two additional investments of $500 each (50 shares at $10 and 40 shares at $12.50). Izabella reinvested all of her dividends. So far, the NAV for her investment has risen from $8 per share to $13.25. Late in the year, she sold 50 shares at $13.25.

What were the proceeds from Izabella's sale of the 50 shares? Round your answer to the nearest dollar. $  

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 $2,160 is divided by 235 shares (145 shares + 50 shares + 40 shares). What was the average price paid by Izabella? Round your answer to the nearest cent. $  

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, 50. What is the total cost basis for Izabella's 50 shares? Round your answer to the nearest dollar. $  

Assuming that Izabella has to pay income taxes on the difference between the sales price for the 50 shares and their cost, how much is this difference? Round your answer to the nearest dollar. $
