The formula y 2.6√x + 11 models the percent of U.S. adults who are considered obese by federal

guidelines, where x is the number of years after 1988, and y is the percent of obese adults. In this equation, y

is already converted from a decimal, so, for example, a 55% obesity rate would correspond to y = 55.

According to this formula, in what year was the obesity rate 16.8 percent?
