Final answer:
The question is asking about the daily energy needs of a person based on their different activities. Activity factors are used to calculate the energy expenditure of each activity level. Multiply the activity factors by the time spent on each activity to find the total energy needs for the day.
Step-by-step explanation:
The question is asking about the daily energy needs of a person based on their different activities. In order to calculate the daily energy needs, we need to assign activity factors to each activity and multiply them by the time spent on each activity.
The activity factor is a multiplier that represents the energy expenditure of each activity level. The given activity factors are: sedentary (1), low active (1.13), active (1.3), and very active (1.42). By multiplying the activity factors with the hours spent on each activity, we can find the total energy needs for the day.
