Answer:
The percentage increase in the puppy's weight is 75%.
Step-by-step explanation:
We can find the percentage increase using the following formula:
[tex]\boxed{\% \space\ \mathrm {increase = \frac{final \space\ - \space\ initial}{initial} \times 100}}[/tex].
In this case,
• initial = 2 kg
• final = 3.5 kg
Substituting these values into the formula:
[tex]{\% \space\ \mathrm {increase = \frac{3.5 \space\ - \space\ 2}{2} \times 100}}[/tex]
⇒ [tex]\frac{1.5}{2} \times 100[/tex]
⇒ [tex]0.75 \times 100[/tex]
⇒ 75%
