How much more was spent, on average, by each person for dogs than cats?

Answer 1

Hello! I can help you with this question! 1,000 millions is equivalent to 1 billion. Therefore, $7,737,600,000 was spend on vet visits for dogs annually. As for cats, $5,913,000,000 were spent on them annually. Divide the price spent on dogs, buy the number of people (31,200,000), and your quotient should be 248. So that’s $240 dollars per person on dogs. For cats, do the same steps. Divide price spent by people (27,000,000), and your quotient should be 219. So that’s $219 dollars per person in cats. Now, you just subtract both prices per person. 240 - 219 = 21. Each person spent $21 more on average for dogs than cats.

Answer 2

$29 million is spent more by each person for dogs than cats.

Explanation:

Amount spent on visits for the dogs = $7,737.6 millions.

Number of dogs owned = 31.2 millions (by bar graph)

∴ On average amount spent on each person =
`(7,737.6)/(31.2) = $248 millions`

Amount spent on visits for the cats = $7,737.6 millions.

Number of cats owned = 27 millions (by bar graph)

∴ On average amount spent on each person =
`(5913)/(27) = $219 millions`

Thus, on average, by each person amount spent for dogs than cats = $248 millions - $219 millions = $29 millions.
