Independent variables, which can be controlled or manipulated; dependent variables, which (we hope) are affected by our changes to the independent variables
Step-by-step explanation:
1000 for 50 is store profit
Answer:
90 and 30 liters
Step-by-step explanation:
1) if solution of 20% is 'x' and of 60% is 'y' liters, then
2) the pure chlorine is: for solution of 20% - 0.2x, for solution of 60% - 0.6y and
3) the mix of the two solutions is 120=x+y.
4) using these items it is possible to make up the system of two equations:

5) finally, x=90 liters of 20%; y=30 liters of 60% solution.
