There are 160 dolls in the store.
Explanation
The ratio of the number of teddy bears to the number of dolls is given as [tex]3:8[/tex]
Suppose, the number of teddy bears [tex]=3x[/tex] and the number of dolls [tex]=8x[/tex]
Given that, the store has 60 teddy bears. That means....
[tex]3x=60[/tex]
[tex]\frac{3x}{3}=\frac{60}{3}[/tex] (Dividing both sides by 3)
[tex]x=20[/tex]
So, the number of dolls in the store [tex]=8x=8*20=160[/tex]
