The equation used to predict the annual sweet potato yield (in pounds per acre) is \(\hat{y}=16,212-0.227 x_{1}+0.212 x_{2}\), where \(x_{1}\) is the number of acres planted and \(x_{2}\) is the number of acres harvested. Use the multiple regression equation to predict the annual sweet potato yields for the values of the independent variables.

(a) \(x_{1}=110,000, x_{2}=100,000\)

(b) \(x_{1}=125,000, x_{2}=115,000\)
