Equation: 11.1 = 3p + 3

2.7 million people

Step-by-step explanation:

We know that the population of the African country in 2011 is 3 million more than 3 times the population in 1950.

Since represents people in millions, we can make the equation

2011 population = 3(1950 population) + 3

The 2011 population was 11.1 and the 1950 population is unknown (p) so:

11.1 = 3p + 3 is our equation.

We can now solve for p by isolating it on one side of the equation.

Subtract 3 from both sides:

$11.1 - 3 = 3p + 3 - 3\\\\8.1 = 3p$

Divide both sides by 3:

$8.1 \div 3 = 3p \div 3\\\\2.7 = p$

Remember, p is in millions of people, so in 1950 the population of the African country was 2.7 million people.

Hope this helped!
