Answer :

Sure, let's go through the detailed steps of solving the question about the total number of tourist arrivals to Mauritius for the period from 2018 to 2021.

### 1) Calculation of Air Arrivals

We are provided with the data for air arrivals each year from 2018 to 2021:
- 2018: 1,359,688
- 2019: 1,338,235
- 2020: 279,325
- 2021: 4,266

To find the total number of air arrivals over these four years, we sum these numbers:
[tex]\[ 1,359,688 + 1,338,235 + 279,325 + 4,266 = 2,981,514 \][/tex]

### 2) Calculation of Sea Arrivals

We are also provided with the data for sea arrivals each year from 2018 to 2021:
- 2018: 39,720
- 2019: 45,253
- 2020: 29,655
- 2021: 201

To find the total number of sea arrivals over these four years, we sum these numbers:
[tex]\[ 39,720 + 45,253 + 29,655 + 201 = 114,829 \][/tex]

### 3) Calculation of Total Tourist Arrivals

The total number of tourist arrivals to Mauritius from 2018 to 2021 includes both air and sea arrivals.

To find the combined total, we add the total air arrivals and the total sea arrivals:
[tex]\[ 2,981,514 + 114,829 = 3,096,343 \][/tex]

### Summary

So, for the period from 2018 to 2021:
- Total number of air arrivals: 2,981,514
- Total number of sea arrivals: 114,829
- Total number of tourist arrivals (air + sea): 3,096,343

These figures provide insights into the flow of tourists to Mauritius over the given period, highlighting how drastically the numbers can change year over year, especially in times of global events impacting travel.
