Kendrick's kennel has 2 spots for cats for every 7 spots for dogs. if he has a total of 144 spots for both cats and dogs then how many more spots does he have for dogs than cats

It is given Kendrick's kennel has 2 spots for cats for every 7 spots for dogs.

Let Kendrick'a kennel has 2x spots for cats.

So Kendrick will have 7x spots for dogs.

Total number of spots for cats and dogs = 2x+7x=9x.

If he has total of 144 spots for both cats and dogs then.

9x=144

Dividing both sides by 9

x=16.

Number of spots for cats = 2x=2 (16) = 32

Number of spots for dogs = 7x=7 (16) = 112.

Number of spots dogs have more than sats = 112-32=80

Kendrick kennel has 80 more spots for dogs than cats.
