Let's analyze the data provided and solve each part of the question step-by-step.
#### 3.1.1 Identify the year where VFR tourists spent the most.
To determine the year where VFR tourists spent the most, we need to compare the spending across all the given years.
Given VFR spending (in thousands) for each year:
- 2017: 610
- 2018: 990
- 2019: 1230
- 2020: 1190
- 2021: 1330
The year where VFR tourists spent the most is 2021, with a total spending of 1330 thousand ZAR.
#### 3.1.2 Calculate the difference in the amounts spent by VFR in 2017 and 2021.
Given the spending amounts for 2017 and 2021:
- 2017: 610 thousand ZAR
- 2021: 1330 thousand ZAR
The difference in the amounts spent by VFR tourists in these years is calculated as:
[tex]\[ 1330 - 610 = 720 \][/tex]
Therefore, the difference in the amounts spent by VFR tourists between 2017 and 2021 is 720 thousand ZAR.
#### 3.1.3 Discuss the spending trend of holiday tourists from 2017 to 2021.
Given holiday spending (in thousands) for each year:
- 2017: 1800
- 2018: 2140
- 2019: 3020
- 2020: 3490
- 2021: 3290
By observing these numbers, we can identify the following trends:
- From 2017 to 2018: Holiday spending increased from 1800 to 2140 thousand ZAR.
- From 2018 to 2019: Holiday spending further increased to 3020 thousand ZAR.
- From 2019 to 2020: Holiday spending continued to rise, reaching 3490 thousand ZAR.
- From 2020 to 2021: There was a slight decrease in spending, dropping to 3290 thousand ZAR.
The overall trend from 2017 to 2021 shows a significant increase in holiday spending, with a peak in 2020. Despite a minor decrease in 2021 compared to 2020, the spending amount in 2021 is still much higher than in the earlier years.
To summarize:
- The year with the highest VFR spending is 2021.
- The difference in VFR spending between 2017 and 2021 is 720 thousand ZAR.
- The holiday spending trend shows a consistent increase from 2017 to 2020, followed by a small decrease in 2021.
The final result is thus:
```
(2021, 720, [(2017, 1800), (2018, 2140), (2019, 3020), (2020, 3490), (2021, 3290)])
```
