Dora counts 6 times as many white kittens as black kittens for sale at the pet store. She counts a total of 20 kittens. How many more white kittens does Dora count than black kittens?

Answer 1

W=6B

W+B = 20

6B+B =20

7B =20

B=20/7 = 2 6/7 black kittens

W =6(20/7) = 120/7 = 17 1/7 White kitten

17 1/7 - 2 6/7 = 14 2/7 more White kittens than Black kittens

Maybe she actually counted 21 total kittens

(could be a typo in the problem)

then she counted 3 Black kittens and 18 White kittens

18-3 = 15 more White kittens counted than Black kittens
