Answer:
12 g of water she use.
Step-by-step explanation:
Given : Jen wants to make 60% salt solution using 18g of salt.
To find : How much water should she use.
Solution : Let x be the solution.
So, 60% of x is 18 g.
∴ ![\frac{60}{100}\times x = 18](https://tex.z-dn.net/?f=%5Cfrac%7B60%7D%7B100%7D%5Ctimes%20x%20%3D%2018)
![x = \frac{18\times 100}{60}](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%7B18%5Ctimes%20100%7D%7B60%7D)
![x = 30](https://tex.z-dn.net/?f=x%20%3D%2030)
Which means Total solution is 30 g and 18 g is the salt
So, quantity of water = 30-18 = 12g
