that answer was wrong, Form a proportion by setting the given ratio of MVD for Country A to the total​ population, x, equal to the ratio of the given MVD per​ 100,000 people for country A.

To form a proportion based on the given ratio of Motor Vehicle Deaths (MVD) for Country A to its total population, let's follow these steps:

1. **Let \( x \) be the total population of Country A.**
2. The ratio of MVD to the total population can be expressed as:
   \[
   \frac{\text{MVD for Country A}}{x}
   \]
3. The given MVD rate is usually expressed per 100,000 people. This means that the proportion for MVD per 100,000 people will be:
   \[
   \frac{\text{MVD for Country A}}{x} = \frac{\text{MVD per 100,000 people}}{100,000}
   \]

4. Now, cross-multiply to solve for \( x \) (the total population):
   \[
   \text{MVD for Country A} \times 100,000 = \text{MVD per 100,000 people} \times x
   \]
   \[
   x = \frac{\text{MVD for Country A} \times 100,000}{\text{MVD per 100,000 people}}
   \]

In this equation, you would plug in the given MVD data to calculate the total population \( x \).

### Example:
If you are given that:
- MVD for Country A = 500 deaths
- MVD per 100,000 people = 25 deaths

The proportion would be:
\[
\frac{500}{x} = \frac{25}{100,000}
\]
Cross-multiply:
\[
500 \times 100,000 = 25 \times x
\]
\[
50,000,000 = 25x
\]
\[
x = \frac{50,000,000}{25} = 2,000,000
\]
So, the total population \( x \) is 2,000,000 people.
