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?

The percent increase since the first visit in the kitten's weight rounded to the nearest percent is 118% and this can be determined by using the unitary method.

Given :

The following steps can be used to determine the percent increase since the first visit in the kitten's weight:

Step 1 - Given that on the first visit to the veterinarian's office, Cora's kitten weighed 550 grams. So, the expression becomes:

= 550

Step 2 - Also given that on the second visit, the kitten had gained 350 grams. So, the above expression becomes:

= 550 + 350

Step 3 - On the third visit, the kitten had gained another 300 grams. So, the above expression becomes:

= 550 + 350 + 300

Step 4 - Simplify the above expression.

= 1200 grams

Step 5 - In the first visit, the weight is 550 grams which is 100% at that time. So, the percent of weight in the third visit is:

Multiply 1200 by 100 in the above expression.

Divide 120000 by 550 in the above expression.

= 218.18%

218%

Step 6 - The percent increase since the first visit in the kitten's weight is:

= 218 - 100

= 118%

Step-by-step explanation:

total increase=350+300=650

amount of oatypop that contains the prize = 40%

amount   of oatypop which doesn't contain the prize = (100-40)=60%

probability that hannah will win a prize

    = s +f s +f f s+ff   f s+ff f f s+ infinity.where f= failure,s= success

=   or 60%

probability that hannah only has to buy 3 or less boxes before getting a prize= (s) and ( f s) and (ff s) and (f f f s)

        = = 87.04 %
