Question

In 2003, the population of an African country was about 15.7 million people, which is 1 million more than 3 times the population in 1950.

Enter and solve an equation to find the approximate population p (in millions) in 1950.

An equation is .

The approximate population in 1950 was million people.

Answer 1

To find the approximate population p (in millions) in 1950, we can set up an equation using the given information. The population in 1950 can be found by solving the equation 15.7 = 3x + 1. The approximate population in 1950 was 4.9 million people.

Step-by-step explanation:

To find the approximate population p (in millions) in 1950, we can set up an equation using the given information. Let's denote the population in 1950 as x.

We know that in 2003, the population was 15.7 million people, which is 1 million more than 3 times the population in 1950. So we can write the equation as:

15.7 = 3x + 1

Now, we can solve this equation to find the value of x, which represents the population in 1950.

Subtracting 1 from both sides of the equation, we get:

14.7 = 3x

Dividing both sides by 3, we get:

x ≈ 4.9

Therefore, the approximate population in 1950 was 4.9 million people
