Answer: The percentage changes is [tex]-11\frac{13}{17} \%[/tex]
Step-by-step explanation:
Since the initial weight of the dog = 17 pounds,
After 3 months, the weight of the dog = 15 pounds,
⇒ [tex]\text{ The percentage in the weight of the dog} = \frac{\text{ Initial weight-final weight}}{\text{ initial weight}}\times 100[/tex]
⇒ [tex]\text{ The percentage in the weight of the dog} = \frac{15-17}{17}\times 100[/tex]
= [tex] -\frac{2}{17}\times 100[/tex]
= [tex] -\frac{200}{17}[/tex]
= [tex] -11\frac{13}{17}\%[/tex]
