Answer: 118%
Step-by-step explanation:
Cora's kitten weighed in the last visit to the veterinarian's office=550 grams
Right now, Cora's kitten weighs =1200 grams
Increase in the kitten's weight=[tex]1200-550=650\text{ grams}[/tex]
Percent increase in weight=[tex]\frac{650}{550}\times100[/tex]
[tex]=118.18\%\approx118\%[/tex]
Hence, there is 118% increase in kitten's weight.
