Answer 1

5-8% of the weight

Explanation:

The dog needs to lose a weight within the values 9-15 pounds

To answer this question, what we just need to do is to know the percentage of 185 pounds that is 9 and the percentage of 185 pounds that is 15

The percentage decrease can be calculated using the formula;

(difference)/old value * 100%

For the 9 pound loss, we have ;

9/185 * 100% = 4.86 which is approximately 5%

For the 15 pound loss, we have;

15/185 * 100% = 8.11% which is approximately 8%

Thus, the dog is losing between 5-8% of its weight
