Question

A vet puts a dog on a diet to lose a half pound every week for 14 weeks. If the dog weighs 145 pounds at the beginning of the diet, what will the dog's final weight be at the end of the diet?

A. 152 pounds
B. 138 pounds
C. 129 pounds
D. 145 pounds

Answer 1

After calculating the total weight loss by multiplying the weekly weight loss (0.5 pound) by the number of weeks (14), we get a total weight loss of 7 pounds. Subtracting this from the dog's initial weight of 145 pounds gives a final weight of 138 pounds.

Step-by-step explanation:

To calculate the dog's final weight after being on a diet, we must consider the amount of weight the vet intends the dog to lose each week, which is a half pound, and the duration of the diet, which is 14 weeks. The total weight the dog is expected to lose over the course of the diet can be found by multiplying the weekly weight loss by the number of weeks:

Weekly weight loss × Number of weeks = Total weight loss

0.5 pound/week × 14 weeks = 7 pounds total weight loss

To find the dog's final weight, we subtract the total weight loss from the initial weight of the dog:

Initial weight - Total weight loss = Final weight

145 pounds - 7 pounds = 138 pounds

Therefore, the dog's final weight will be 138 pounds after 14 weeks of diet, which corresponds to answer choice B.
