Answer:
The solution of Timmy is saltier.
Step-by-step explanation:
We have to keep in mind that a solution is saltier if and only if salt has a greater proportion within solution. The following criterion is used to determine which solution is saltier:
Where:
- Salt ratio, dimensionless.
- Parts of salt, dimensionless.
- Parts of water, dimensionless.
Now, we find the salt ratios of Patty and Timmy:
Patty ( and
)
Timmy ( and
)
The solution of Timmy is saltier.
