Solve the problem. A reasonable quadratic model for the population of a certain city is found to be 
where B(t) is the population (in thousands) of the city in the year that is t years since 2012. A reasonable quadratic model for the number of residents of that city who were born outside the United States is 
where F(t) is the number (in thousands) of foreign-born residents of the city in the year that is t years since 2012. Let P(t) be percentage of residents of the city who were born outside the United States in the year that is t years since 2012. An
equation for P is P(t) = 
. Use P to predict when the city will have 15.3% foreign-born residents.
