Answer:
12%
Explanation:
First, find how much salt is in each solution by multiplying the total amount by the percent of salt:
10(0.15)
= 1.5
15(0.1)
= 1.5
Added together, there are 3 pints of salt. There is a total of 25 pints, since 10 pints and 15 pints were mixed.
Find the concentration of salt by dividing 3 by 25
3/25
= 0.12
So, the concentration of salt in the solution is 12%
