Answer 1

There are 160 dolls in the store.

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....

$3x=60$

$\frac{3x}{3}=\frac{60}{3}$ (Dividing both sides by 3)

$x=20$

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