Electronic cigarette sales have grown approximately exponentially from 0.03 million units in 2008 to 3.6 million units in 2011. Each unit has three parts: battery, charger, and nicotine-containing cartridge. Let f(t), where t is the number of years since 2008, be the exponential function that models the growth. Predict in which year sales will reach 1.253 billion units. Sales will reach 1.253 billion in (Round down to the nearest integer. Round all intermediate values to the nearest hundredth as needed.)
