Zoe counts 5 times as many black kittens as white kittens for sale at the pet store. she counts a total of 25 kittens how many m

malfutka [58]

Let us say that:

a = black kittens

b = white kittens

We know that:

a = 5 b

a + b = 25

Therefore:

5 b + b = 25

6 b = 25

b = 4.17

But we cannot have a fraction value for the number of kittens, so round off:

b = 4

So a is:

a = 25 – 4 = 21

Hence Zoe counts additional 1 black kitten.
