The answer is square root of 72
For this case we have that, the cost of 5 dolls is $130. If we want to know the number of dolls that can be bought with $390 we make a rule of three:
5 dolls -----------> $130
x --------------------> $390
Where the variable "x" represents the number of dolls that can be purchased with $390.
![x = \frac {390 * 5} {130}\\x = 3 * 5\\x = 15](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%20%7B390%20%2A%205%7D%20%7B130%7D%5C%5Cx%20%3D%203%20%2A%205%5C%5Cx%20%3D%2015)
Thus, you can buy 15 dolls.
