Two years ago, Izabella Martinez, from Atlanta, Georgia, invested $$880$ by buying $110$ shares $($$$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 $$13\mathrm{.}75.$ Late in the year, she sold $70$ shares at $$13\mathrm{.}75.$

What were the proceeds from Izabella's sale of the $70$ 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 $$1,880$ is divided by $200$ shares $(110$ 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, $70.$ What is the total cost basis for Izabella's $70$ 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 $70$ shares and their cost, how much is this difference? Round your answer to the nearest dollar.
