x
)
Step-by-step explanation:
In order to solve the amount of each solution, we need to set up equations. We do as follows:
Let x = solution with 32% sodium
y = solution with 12% sodium
Overall balance
x + y = 50
Component balance
.32x + .12y = 50(.20) =10
Solving simultaneously,
x = 20
y = 30
Hope this answers the question. Have a nice day.
