Answer:
Step-by-step explanation
Given the following
Weight of Mary's dog = 185pounds
If her dog looses 9pounds
Percentage of weight lost = 9/185 * 100
Percentage of weight lost = 900/185
Percentage of weight lost = 4.86%
Percentage of weight lost will be approximately 5%
If her dog looses 15pounds
Percentage of weight lost = 15/185 * 100
Percentage of weight lost = 1500/185
Percentage of weight lost = 8.10%
Percentage of weight lost will be approximately 8%
Hence Mary's dog will lose weight between 5% and 8% with respect with the total weight
