Question 278645: doreen schmidt is a chemist. she needs to prepare 32 ounces of a 13% hydrochloric acid solution. find the amount of the 16% solution and the amount of 8% solution she should mix to get the solution Answer by nyc_function(2741) (Show Source):
You can put this solution on YOUR website! Here is your equation:
Let x = amount at 16%
Let y = amount at 8%
x + y = 32...This is your first equation.
0.16x + 0.08y = 32(0.13)...This is your second equation.
What we have here is the classic case of two equations in two variables.
