The graph represents a linear relationship between dollars ($) and kroner (kr), showing how many kroner one must pay to get a certain amount of dollars. Let's analyze it and address the questions:

1. **From the graph**, for 20 dollars, you need 200 kroner. So, the exchange rate can be calculated as:

\[
\text{Exchange rate} = \frac{200 \text{ kr}}{20 \text{ dollars}} = 10 \text{ kr per dollar}.
\]

### First Question: "Hvor meget skal man betale for 100 dollars?" (How much should you pay for 100 dollars?)

If 1 dollar = 10 kroner, then for 100 dollars:

\[
100 \text{ dollars} \times 10 \text{ kr/dollar} = 1000 \text{ kroner}.
\]

Thus, you would pay **1000 kr** for 100 dollars.

### Second Question: "Hvor mange dollars får man for 420 kr?" (How many dollars do you get for 420 kr?)

Using the same exchange rate (1 dollar = 10 kroner), for 420 kroner:

\[
\frac{420 \text{ kroner}}{10 \text{ kr/dollar}} = 42 \text{ dollars}.
\]

So, you would get **42 dollars** for 420 kroner.

### Summary:
- For 100 dollars, you would pay **1000 kr**.
- For 420 kroner, you would get **42 dollars**.

2. What would you pay for 150 dollars with the same exchange rate?
3. If the rate changed to 12 kr per dollar, how much would 100 dollars cost?
4. How many dollars would you get for 600 kr with the current exchange rate?
5. How does a change in exchange rate affect the cost of buying foreign currency?

**Tip:** Always double-check exchange rates before making transactions, as rates fluctuate frequently.
