To determine the total number of calories in the entire bag of chips, we need to carefully follow these steps:
1. Identify the calories per serving: We know that each serving of chips (6 chips) contains 20 calories.
2. Identify the number of servings per bag: The bag contains 20 servings.
3. Calculate the total calories in the bag: To find the total calories in the whole bag, we need to multiply the number of calories per serving by the number of servings in the bag.
So, to perform the calculation:
[tex]\[ \text{Total calories} = \text{Calories per serving} \times \text{Number of servings} \][/tex]
[tex]\[ \text{Total calories} = 20 \, \text{calories/serving} \times 20 \, \text{servings} \][/tex]
[tex]\[ \text{Total calories} = 400 \, \text{calories} \][/tex]
Therefore, if someone ate the whole bag, they would consume 400 calories in total.
The correct answer is:
400 calories
