Final answer:
Sophie's TEE, with a BMR of 1,500 calories and moderate exercise, would be calculated by multiplying her BMR by the physical activity factor of 1.55, resulting in C. 2,325 calories.
Step-by-step explanation:
The subject in question involves calculating the Total Energy Expenditure (TEE) based on Sophie's Basal Metabolic Rate (BMR) and her level of physical activity. In this case, Sophie's BMR is 1,500 calories. The Physical Activity (PA) factor for moderate exercise usually ranges from 1.55 to 1.75. To calculate TEE, you multiply the BMR by the PA factor. If we choose a moderate value within this range, for example 1.55, Sophie's TEE would be:
BMR × PA factor = TEE
1,500 calories × 1.55 = 2,325 calories
This calculation provides an estimate of the total number of calories she would need to maintain her current weight with her current levels of activity. If Sophie exercises moderately, based on the calculation above, the correct answer would be (C) 2,325 calories.
