Answer:
Number of jars filled is 3
(approximately 4).
Step-by-step explanation:
Initial amount of salt = 1/2 cup.
Amount of salt left = 1/9 cup.
Amount of salt used = 1/2 - 1/9
= ![\frac{9-2}{18}](https://tex.z-dn.net/?f=%5Cfrac%7B9-2%7D%7B18%7D)
= 7/18
The size of each jar = 1/10 cup.
Amount of salt used = size of the each jar x number of jars filled
7/18 = 1/10 x number of jars filled
number of jars filled = 7/18 ÷ 1/10
= 7/18 x 10/1
= 70/18
= 3 ![\frac{8}{9}](https://tex.z-dn.net/?f=%5Cfrac%7B8%7D%7B9%7D)
= 3.9
The number of jars filled is approximately 4.
