Answer:
28 rabbits
Step-by-step explanation:
From the statement, you can write the following:
d+c+r= 126
d=dogs
c= cats
r= rabits
Then, you have that there are 13 cats and that three fourths of the remaining animals are dogs:
c=13
d=(126-13)*(3/4)= 113*(3/4)= 85
Now, you can isolate r, to find the number of rabbits:
r=126-d-c
r= 126-85-13
r= 28
According to this, the are 28 rabbits.
