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=\(1200-550=650\text{ grams}\)
Percent increase in weight=\(\frac{650}{550}\times100\)
\(=118.18\%\approx118\%\)
Hence, there is 118% increase in kitten's weight.
