BH 20% 30% 40% 5% 5%
BF 3% 2% 60% 20% 15%
MB 5% 5% 15% 60% 15%

BF - Represents 10% of production employees
MB - Represents 40% of production employees
WC - Represents 25% of production employees

In september 1998 the population of the country of West Goma in millions was modeled by f(x)= 16.9e^0.0019x. At the same time the population of East Goma in millions was modeled by g(x)=13.5e^0.0106x. In both formulas x is the year, where x=0 corresponds to September 1998. Assuming these trends continue, estimate what the population will be when the populations are equal.
