SOLUTION: A chemist wishes to mix a 10% acid solution with a 60% acid solution to obtain 300 quarts of a 24% acid solution. How many quarts of each solution should be mixed together?

Question 928216: A chemist wishes to mix a 10% acid solution with a 60% acid solution to obtain 300 quarts of a 24% acid solution. How many quarts of each solution should be mixed together?
Answer by TimothyLamb(4379) (Show Source): You can put this solution on YOUR website!
x = quarts of 10% solution
y = quarts of 60% solution
---
10x + 60y = 24*300
x + y = 300
---
put the system of linear equations into standard form
---
10x + 60y = 7200
x + y = 300
---
copy and paste the above standard form linear equations in to this solver:

answer:
x = quarts of 10% solution = 216
y = quarts of 60% solution = 84
