Problem Description:
The image shows four New Zealand banknotes with denominations of $5, $10, $20, and $50. The task is to solve a problem related to these banknotes. Since the specific problem isn't explicitly stated in your question, I will infer a common type of problem involving currency and provide a solution.
#### Inferred Problem:
Suppose you have a total of
$100 in New Zealand dollars, and you want to use the fewest number of banknotes possible to make this amount. Determine how many of each denomination ($5, $10, $20, $50) you should use.

Solution:
To minimize the number of banknotes, we should prioritize using the highest denomination first and work our way down to lower denominations. Here's the step-by-step process:
1.
Start with the highest denomination:
- The highest denomination available is
$50.
- How many $50 notes can we use without exceeding $100?
- Using 2 × $50 = $100.
- This exactly matches the target amount of $100.
2.
Check if any remaining amount needs to be covered:
- After using 2 × $50, the total is $100, so there is no remaining amount to cover.
3.
Verify the solution:
- Using 2 × $50 notes gives us exactly $100.
- No other combination of lower denominations would result in fewer banknotes (e.g., using $20 or $10 notes would require more than 2 banknotes).
---
Final Answer:
To make $100 using the fewest number of banknotes, you should use:
-
2 × $50 notes.
Thus, the solution is:
\[
\boxed{2 \text{ × } \$50}
\]
