Breakfast cereal is an important source of fiber in their diets. Cereals also contain potassium, a mineral shown to be associated with maintaining a healthy blood pressure. An analysis of the amount of fiber (in grams) and the potassium content (in milligrams) in servings of 77 breakfast cereals produced the regression model y = 35 + 28x, where x denotes fiber, and y denotes potassium.If your cereal provides 9.4 grams of fiber per serving, how much potassium does the model estimate you will get?
