Answer 1

There are 160 dolls in the store.

Step-by-step explanation

The ratio of the number of teddy bears to the number of dolls is given as
`3:8`

Suppose, the number of teddy bears
`=3x` and the number of dolls
`=8x`

Given that, the store has 60 teddy bears. That means....

`3x=60`

`(3x)/(3)=(60)/(3)` (Dividing both sides by 3)

`x=20`

So, the number of dolls in the store
`=8x=8*20=160`
