The covid-19 cases in 2020 were 9.1 per 100000 people.
How many covid-19 cases were there in total if the total population of south at the time was 39 million? Show all calculations.

Answer 1

To find the total number of COVID-19 cases in the South in 2020, we can use the given rate of infection and the total population.

1. **Identify the rate of cases and population:**
- Rate of cases: 9.1 per 100,000 people
- Total population: 39 million (which is equal to 39,000,000 people)

2. **Calculate the number of cases per person:**
To find the number of cases for 39 million people, we need to first convert the population into groups of 100,000.

\[
\text{Number of groups of 100,000} = \frac{\text{Total Population}}{100,000} = \frac{39,000,000}{100,000} = 390
\]

3. **Calculate the total number of cases:**
Now, we can multiply the number of groups of 100,000 by the rate of cases per group.

\[
\text{Total Cases} = \text{Number of groups} \times \text{Rate of cases} = 390 \times 9.1
\]

\[
\text{Total Cases} = 390 \times 9.1 = 3,549
\]

Thus, the total number of COVID-19 cases in the South in 2020 was **3,549 cases**.
