The annual rice yield (in pounds), is given by the equation y-hat = 859 + 5.76a + 3.82b, where ‘a' is the number of acres planted (in thousands), and ‘b' is the number of acres harvested (in thousands). Predict the annual rice yield (in pounds) when the number of acres planted is 3275 (in thousands) and the number of acres harvested is 2980 (in thousands).
