Step 1: Identify the description that is represented by a discrete graph.
A discrete graph is a type of graph that consists of distinct, separate points. It does not contain any continuous curves or lines connecting the points. The only option in the given descriptions that can be represented by a discrete graph is option C, as it involves adding distinct, separate quantities (calories from an egg and calories from cereal).
Step 2: Calculate the total calories consumed by Juan.
We are given that Kiley ate an egg with 78 calories and some cereal with 110 calories per serving for breakfast. Let's assume that Juan ate one serving of cereal. Therefore, the total amount of calories he consumed is: Total calories = Calories from egg + Calories from cereal = 78 calories + 110 calories = 188 calories
Final Answer
Juan consumed a total of 188 calories for breakfast.
