Answer:

50 grams of fat

Step-by-step explanation:

The equation of the line generated by the regression is  

Calories = 110 + 10 (grams of fat), where grams of fat is a variable.  

Since the value of the grams of fat is multiplied by 10, if the two cereals differ by 5 grams of fat per serving, then the caloric content per serving will differ by:

10 x 5 = 50 grams of fat
