Centers for Disease Control and Prevention data from 2010 and projected to 2050 indicate that adult diabetes in the United States could dramatically increase. With x equal to the number of years after 2000, the percent of U.S. adults with diabetes can be modeled by

y = -13.0 + 11.9 ln x

Use the model to find the year in which the percent of U.S. adults with diabetes is predicted to reach 30%.
