Question

A certain pet store sells 6 times as many fish as kittens. It sells twice as many kittens as lizards. If the pet store sells 15 lizards a week, how many fish, kittens, and lizards does the pet store sell every week?

Answer 1

They sell 225 pets each week.

Explanation:

Let f be fish, k be kittens, and l be lizards.

`f`÷6=
`k`

`k`÷2=
`l`

If
`l=15`, then:

`k=30\\f=180`

180+30+15=225 pets

They sell 225 pets each week.

(I hope this isn't wrong but that answer seems wrong)

Answer 2

It sells twice as many kitten as lizards:

Kittens sold = 15 x 2 = 30 total kittens.

It sells 6 times the amount of fish:

Fish sold = 6 x 30 = 180 total fish.

Lizards = 15

Kittens = 30

Fish = 180
