In Russia, the average consumer drank two servings of
Coca-Cola
in 1993. This amount appeared to be increasing exponentially with a doubling time of  2 years. Given a long-range market saturation estimate of 100 servings per year, find a logistic model for the consumption of Coca-Cola in Russia, and use your model to predict when, to the nearest year, the average consumption reached 50 servings per year.
