Final answer:
Ladybird, Ms. Catall's dog, has lost a total of 4 pounds over 4 weeks by losing 1 pound per week.
Step-by-step explanation:
The student's question involves calculating total weight loss over a given time period. Ms. Catall's dog Ladybird has been losing weight at a consistent rate of 1 pound per week, and they have been at this for 4 weeks. Since the rate of weight loss is 1 pound per week, to calculate the total weight loss, we simply multiply the rate by the number of weeks.
So, the total weight loss is:
- 1 lb/week × 4 weeks = 4 lbs
This means that Ladybird has lost a total of 4 pounds over the course of 4 weeks.
