Answer 1

Option D

Answer:

Shelter 4 has the highest percentage of black cats with 72%.

Solution:

Let us find the percentage of cats in each shelter of Marnie

Step 1:

4 of the 18 cats in Shelter 1 were black

This can be written as

$\frac{4}{18}$ = 0.22  

Step 2:

13 of the 24 cats in Shelter 2 were black

$\frac{13}{24}$ = 0.54  

Step 3:

12 of the 20 cats in Shelter 3 were black

$\frac{12}{20}$ = 0.60  

Step 4:

18 of the 25 cats in Shelter 4 were black

$\frac{18}{25}$ = 0.72  

Result:

Therefore we can conclude Shelter 4 has the highest percentage of black cats with 72%.
