To find the population 7 years from now, we need to add 7 to the current time, so t=7. Then we can plug in t=7 into the given population model:
Population = 11eac9cf_f893_5679_a07b_0b999f5239fd_TB7816_11 = 11e^(0.042(7)) = 11e^0.294
Rounding to the nearest thousandth, we get a population of approximately 14.15 thousand people. Written in scientific notation, this is 11eac9cf_f893_a49b_a07b_fd262310f8ad_TB7816_11. Therefore, the best choice is B).
