For many people, breakfast cereal is an important source of fiber in their diet. Cereals also contain potassium, a mineral shown to be associated with maintaining a healthy blood pressure. And analysis of amount of fiber (in grams) and the potassium content (in milligrams)  in servings of 77 breakfast cereals produce the regression model Potassium =39+26 Fiber. If your cereal provides 10 g of fiber per serving, how much potassium does the model estimate you will get? ___Milligrams of potassium
