Two years ago, Izabella Martinez, from Atlanta, Georgia, invested $$1,200$ by buying $150$ shares $($$$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 $$12\mathrm{.}50).$ Izabella reinvested all of her dividends. So far, the NAV for her investment has risen from $$8$ per share to $$13\mathrm{.}50.$ Late in the year, she sold $80$ shares at $$13\mathrm{.}50.$

What were the proceeds from Izabella's sale of the $80$ 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 $$2,200$ is divided by $240$ shares $(150$ 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, $80.$ What is the total cost basis for Izabella's $80$ 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 $80$ shares and their cost, how much is this difference? Round your answer to the nearest dollar.
