x liters of 3% 3-x liters of 10$ .03x + .10(3-x)= .079(3)

ok do I solve for x and y? to get the concentrations from the 3& and the 10% bags?

30x+100(3-x)=237 30x+300-100x=237 -70x=-63 x=.9 liters of 3% solution 3-x = 2.1 liters of 10 % solution

First multiply by 1000 to get rid of the decimals.

ok , I got x = 0.9

so that will be concentration from the 3% bag right? then I need to find the concentration from the 10% bag correct?
Mertsj
  • Mertsj
Good!! That is the amount of 3% solution that is needed.
