Final answer:
To find out the calorie content for three cheese flavored rice cakes, we calculate it based on the information that four contain 180 calories, leading to the determination that three rice cakes have 135 calories.
Step-by-step explanation:
The question is based on calculations to determine the number of calories in three cheese flavored rice cakes based on the information that four rice cakes contain 180 calories. To determine how many calories are in three rice cakes, we would use a simple proportion where if four rice cakes equal 180 calories, then one rice cake would have 45 calories (180 calories divided by 4). Therefore, three rice cakes would contain 135 calories (45 calories multiplied by 3).
This understanding of calorie content, energy input, and dietary choices can help a person assess their intake of food and its impact on health and the environment. For instance, the fact that a person needs 2,000 kcal of metabolic content per day and to obtain that from rice alone would require a tremendous amount of food gives perspective on the energy efficiency of different food sources.
