Write an equation. Then, solve and check.
-The population of a city is 4 million. It is estimated that this is about $\frac{2}{3}$ of the projected population fifty years later. What is the projected population of the city?
A) $4=\frac{2}{3} x ; x=2 \frac{2}{3}$ million people
B) $4=\frac{2}{3} x ; x=6$ million people
C) $4=x-\frac{2}{3} ; x=4 \frac{2}{3}$ million people
D) $x=\frac{2}{3} \cdot 4 ; x=2 \frac{2}{3}$ million people
