Answer
$$80 million $$
Work Step by Step
1. Look on the x-axis and find the year 2050.
2. Find the point at which the red line intersects with the line above 2050, and find the y value for that point.
3. Since, the y value is 80 and the unit of the y-axis is millions of people, the population in the year 2050 would be 80 million.
