The population of country A in millions is modeled by $f ( x ) = 16.8 \mathrm { e } ^ { 0.0019 x }$. During the same time period, the population of country B in millions is modeled by $g ( x ) = 13.3 e ^ { 0.0124 x }$. In both formulas $x$ is the number of years. Assuming these trends continue, estimate what the population will be when the populations are equal. Round to the nearest million.
A) 16 million
B) 18 million
C) 17 million
D) 1 million
