How do you calculate food servings?

Hi everyone, I am so lost. I am suppose to calculate the nutritional values of a clmate's 7 day diet for my Nutrition cl. I also need to fill the food servings. I think I just don't understand how to go about this. Okay, example my person ate Raisin Bran Crunch 2 cups, and on the label it saids Serving Size 1 cup (53.0 g). So in the box under Whole Grain's category do I put 2 cups? Or do I put 106 g (53 g x 2)? Or do I put 2 servings? Please help because I think I might be thinking too much into this.
