Question

On the first visit to the veterinarian's office, Cora's kitten weighed 550 grams. On the second visit, the kitten had gained 350 grams. On the third visit, the kitten had gained another 300 grams. What is the percent increase since the first visit in the kitten’s weight, rounded to the nearest percent?

Answer 1

To calculate the percent increase in the kitten's weight since the first visit, we find the total weight gained (650 grams) and divide it by the initial weight (550 grams), and then multiply by 100 to get the percent increase, which is approximately 118% when rounded to the nearest percent.

Step-by-step explanation:

The question asks for the percent increase in the kitten’s weight since the first visit to the veterinarian. To find this, we need to calculate the total gain in weight and compare it to the initial weight. The kitten initially weighed 550 grams. On the second visit, it had gained 350 grams, and on the third visit, it gained another 300 grams.

First, we find the total weight after three visits:

1. 
   
3. Initial weight: 550 grams
4. 
   
6. Gained weight second visit: 350 grams
7. 
   
9. Gained weight third visit: 300 grams
10. 
    
12. Total weight after third visit: 550 + 350 + 300 grams = 1200 grams

Next, we calculate the total weight gained:

Total gain = Second visit gain + Third visit gain = 350 grams + 300 grams = 650 grams

Now, we find the percent increase by using the formula:

Percent Increase = (Total weight gain / Initial weight) × 100

Percent Increase = (650 grams / 550 grams) × 100 ≈ 118.18%

We then round to the nearest percent:

Rounded Percent Increase = 118%
