On 2013-05-03 one Euro (€) was buying 1.3109 US Dollars ($) and 0.8431 British Pounds (£). At Frankfurter Börse around noon adidas AG was the largest winner compared with the day before with a price of € 84.8492 per share. If you buy 31 shares, how much are they worth in $?

The worth in $ is the number of shares $\times$ stock price $\times$ exchange rate, i.e., $31 \times 84.8492 \times 1.3109 \approx 3448.0933047$.

The worth in £ is the number of shares $\times$ stock price $\times$ exchange rate, i.e., $85 \times 84.8492 \times 0.8431 \approx 6080.5906442$.

The worth in € is the number of shares $\times$ stock price $\times$ exchange rate, i.e., $99 \times 84.8492 \times 1 \approx 8400.0708$.
