B2. The table shows the exchange rate of various foreign currencies $\mathrm{v}$ in euros. The exchange office does not charge any additional fees for currency exchange.

A. How many Swiss francs do we get for 15 euros? Express the result to the nearest cent.

| EXCHANGE RATE |  |
| :--- | :--- |
| Currency | Value $\mathbf{v} \boldsymbol{€}$ |
| Croatian kuna | 0.13 |
| Japanese yen | 0.0075 |
| Swiss franc | 0.93 |
| US dollar | 0.91 |
| British pound | 1.38 |

B. The price of a Big Mac at McDonald's is 2.69 British pounds in London and 4.60 US dollars in New York. Justify with calculations which city has the more expensive Big Mac when the prices are converted to euros using the table above, and by what percentage.

C. Daichi exchanged 1000 Croatian kunas for Japanese yen. How many yen did he receive?

D. In the neighboring exchange office, the value of the Croatian kuna is 0.12 euros, but the exchange office charges a commission of 100 kunas. What is the minimum amount of euros we need to exchange so that the currency exchange in the neighboring exchange office is profitable?
B2. For 1 Swiss franc, we get 0.93 EUR, and for 1 EUR, we get $\frac{1}{0.93}$ francs. For 15 EUR, we get $15 \cdot \frac{1}{0.93} \approx 16.13$ francs.

According to the exchange rate list, both prices are converted to EUR: 2.69 pounds is 3.71 euros, and 4.60 dollars is 4.19 euros. The Big Mac is 12.9% more expensive in New York.

For 1000 kuna, he received 130 euros or 17333 yen.

According to the exchange rate list, for $x$ euros, we get $\frac{x}{0.13}$ kuna, and at the neighboring exchange office, we get $\frac{x}{0.12}$ kuna, but we pay 100 kuna in fees. We write the equation $\frac{x}{0.13}=\frac{x}{0.12}-100$. The equation has a solution of 156 euros. If we exchange more than 156 euros, the exchange will be more favorable at the neighboring exchange office.

A. For 15 EUR, we get 16.13 francs. .................................................... 1 t
