1 answer

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.
