Final answer:
To determine how much weight was lost, subtract the previous weight of 164 pounds from the current weight of 148 pounds, which equals 16 pounds lost.
Step-by-step explanation:
The question is asking to calculate the weight loss of a patient between two visits. To find how much weight the patient lost, we subtract the weight from the last visit from the current weight. So, if the patient weighed 164 pounds last visit and now weighs 148 pounds, the weight loss is calculated as follows:
164 lbs – 148 lbs = 16 lbs.
Therefore, the patient lost 16 pounds between visits.
