It’s D, y = 4.
have a good day :)
So, let's say that all the dogs had a number of x.
then 1/12 x were the Hound Group dogs.
then, out of the Hound Group,, that is 1/12 x, 3/10 were English Foxhounds.
For this, we need to multiply the fractions:
so of all the dogs at the show, the English Foxhunds were a 1/40 fraction,
A) 20.9
b) (230 + x) / 12 = 22
230 + x = 264
x = 34 years old
